Best Aquarium Salt to Keep Your Fish Healthy


We all love our fish and wish them  long, healthy lives. A common way to accomplish is this is through using aquarium salt products and adding them to the water they swim in. As you have probably already discovered by now, choosing a quality aquarium salt is no easy task. There is a plethora of products available on the market, and it can be daunting or even overwhelming to make your pick.

Considering how salt treatment itself needs a little tinkering in order to be effective, as it can be toxic and dangerous in large doses, you are probably at a loss by now. Luckily for you, this article will give you all you need to know. First, we will explain whether you should or shouldn’t add salt to your aquarium. Second, we will outline some principles for proper salt use. Third, we will showcase our favorite aquarium salt products. We have personally tried all these and cannot recommend them enough. But first:

Should you Add Aquarium Salt?

The only true answer is that it depends. Generally, adding a bit of salt to a freshwater aquarium aids fish and increases their well being and health. For some fish, however, salt can be toxic. Moreover, any salt treatment should be accompanied by regular water changes to keep salt levels from rising to dangerous levels.

Depending on what fish you have in your aquarium, what you are trying to accomplish – prevention or treatment – as well as depending on where you live – water “softness” differs in different locations – you should calibrate the amount of salt you add to your aquarium accordingly.

We therefore encourage you to perform your own, individual treatment to gauge the salt levels suitable for your specific goals and fish. Giving you exact guidelines would be irresponsible, or even dangerous to your fish.

Principles of Effective Salt Treatment

What we can do, however, is to give you some general principles you can apply in your salt treatment, that you are likely to find useful, no matter your situation.

  • Salt Treatment & Parasites: Regular use of salt as a preventative, can end up making parasites resistant to salt treatment. You might then have to resort to medications, instead. Thus, use salt no more than necessary.
  • Salt & Aquatic Plants: Many aquatic plants cannot really handle large amounts of salt. That being said, most should be fine with a little aquarium salt.
  • General rule of thumb: Like we mentioned, the exact amount of salt you should use depends on factors specific to your own situation. If we were to give a general rule of thumb, we could recommend you start with 1 tablespoon per 7 gallons of water – this is generally considered a safe dose for most fish and aquatic plants.
  • Always follow the product’s guidelines: While salt treatment can be a highly beneficial and inexpensive preventative method, we cannot stress enough the importance of following a salt product’s guidelines. Do not exceed the recommended doses, as doing so will result in many negative consequences you would do best without.

Tropical Marine Fish Depression Signs

Introduction to Underwater Depression

It may sound strange at first how aquarium fish, seemingly enjoying a life of tranquility and abundance, may exhibit strong signs of depression and stress. You would think that being taken of as much as they usually are, they would be relatively stress immune. Unfortunately, signs of depression and stress can manifest on all living things of this Earth and our underwater friends are no exception. Much like us humans, fish under long stretches of stress can develop serious health complications and severe problems – and the matter of fact is, such cases are much more widespread and common than one would think.

Perhaps the biggest contributing factor towards their depression is how fish take quite the leap in their lifestyles when brought from the wild all the way to an aquarium. They experience all kinds of stresses, like changes in their diets, the conditions of the water they live in or even a lack of space for them to swim in. Not least among these factors, is how fish are highly social animals and being forced to considerably limit their social life heavily impacts them.

Identifying the leading causes of depression and stress

To better understand how fish develop depression, it is vital to understand what causes it in the first place. While treating sick fish is certainly possible, the best kind of medicine is preventing the sickness from taking root. Whether you already have tropical marine fish in your at-home aquarium or you are planning to get them, you would do well to address the following factors to ensure they live long and happy lives and avoid unnecessary harm:

  • Low oxygen levels: Should oxygen levels fall bellow the recommended level, fish are forced to use far more than what is optimum for their health. In extreme cases, this can even cause death. In any case, improper oxygen levels is a sure way to inflict chronic or acute stress on your fish.
  • Inadequate tank size: While the notion that “fish grow to the size of their tanks” is certainly a myth, it is established that fish who live in tanks too small for them and generally low quality living conditions become stunted in their growth and unhealthy.
  • Fluctuations in temperature: The vast majority of tropical and marine fish have problems with sudden temperature changes. The daily fluctuations produced by tanks that have not been set up properly can inflict significant chronic stress on the fish, whether the temperature is too high or too low.
  • Improper nutrition: Even though many fish are robust enough to survive a less than ideal diet it absolutely does them no good and negatively impacts their well-being. The effects of malnutrition are many and you should really pay attention to how much and what kinds of food your fish eat.
  • Harassment from other fish: On their natural environment, fish have plenty of room to navigate around and many hiding places to protect them. In a small yet crowded aquarium, however, chances are they likely to have conflicts with neighbor fish – and no place to hide. In-fighting among fish is not uncommon. It is part of their nature. Being left helpless against the aggressor fish, however, and being unable to hide is certainly a big cause of stress for them.

Signs to look out for

There is a great deal of revealing signs for you to look out for on your fish to see if they suffer from depression. These fall under the following categories: Differences in their swimming activities, having issues with their appetite, a change of their colors, changes in their breathing rate and how aware they seem of their surroundings.

  • Swimming activities: The most common indication is called the “shimmy” – the fist looks as if it is swimming really fast yet fails to move, practically staying in the same place. Other indicators are generally out of the norm swimming practices: Frantic swimming all over the aquarium is a sure sign of duress. Reversely, a significant decrease in swimming indicates weakness and should raise your red flags.
  • Appetite: Stress triggers a fish’s fight or flight reflexes. A highly stressed fish is constantly on the look out for danger instead of looking around for nutrition. This eventually depletes its energy stores causing it to become weak and susceptible to all kinds of hazards. It is a vicious cycle: The fish’s appetite drops due to stress, and because it does not eat nearly enough it accumulates even more stress.
  • Color: Closely related to a drop in appetite, colors beginning to fade are a sure sign that you fish suffers. Maintaining the beautiful colors your fish sport is quite the costly endeavor for their organisms: When they stop having adequate energy intake through their diets, their coloring is one of the first victims to suffer.
  • Respiration: Our breathing rate increases when faced with stress or adversity – this happens due to our natural fight or flight instincts. An increase in respiration consequently increases the concentration of available oxygen, which aids us when dealing with potentially dangerous situations. Fish have an extremely efficient system of respiration. Unfortunately, it is quite susceptible to infections, disease or plain poor water quality: These cause their gills to produce mucus which in turns decreases the gills’ function and thus causes fish to essentially breathe faster, considerably tiring and weakening them in he long term.
  • Awareness: Acute changes in a fish’s mentation, whether they lean on the side of dullness or overt stimulation are a red flag for distress. Generally, a depressed fish is more likely to be laying still and drifting around instead of racing the aquarium in agitation. In both cases, however, out of the norm activity should be considered a sign of distress. You should take great care to note your fish’s activity levels to be able to deduce whether there is a sudden change or not. It is very important to keep in mind that there is a rather large variation among the many different species of fish, with some being more active than others.

What Should I Feed my Fish?

Fish food pellets in hand close-up. carp, child, closeup

Isn’t it weird that while you’re sitting down drinking a Dr. Pepper and eating a slice of cheese pizza you’re trying to determine the absolute healthiest food to feed your fish? Many fish-keepers obsess over what they need to feed their fish. In this article we will discuss the best brands of food, which types of food to feed to different fish and also brands to avoid. This will only discuss pellets, flakes and freeze-dried foods. Not every single brand will be listed so if you have a specific question, feel free to message me on Facebook!

Before we get started though, there are a few things you should keep in mind.

  • Foods that have ‘meals’ (fish meal, squid meal, shrimp meal, vegetable meal, etc.) as the first ingredient are typically lower quality.
  • Foods that begin their ingredient list with ‘whole’ foods (whole Atlantic krill, whole fish, whole shrimp) are almost always high-quality foods.
  • Using natural ingredients like garlic, real seaweeds, different kinds of algae are all signs that the food you’re looking at is of high-quality. Enriching the food with different vitamins is also a common practice in more expensive fish foods.
  • Some fish, like Figure Eight Puffers, need a specialized diet which is something you’ll need to research on your own.

Below-Average Food Brands:

In no specific order, here are the brands of fish food you often see which I think you should avoid. These foods are typically cheaper and use more fillers and less, if any, premium ingredients. Often times, companies will use fillers like wheat to cut costs. Regardless of what specific food they’re selling, I won’t purchase any food from these brands.

  • Tetra
  • Aqueon
  • API
  • Marineland
  • Wardley’s

Average/Above-Average Food Brands:

These brands of food are better quality than those listed above, whilst some of their foods will use fillers, often times they use less fillers and more quality ingredients. Often times, their freeze-dried products will be enhanced with vitamins whereas the cheaper brands will not be. A good example of this is Hikari’s Bloodworms vs Tetra’s. The main difference is that Hikari enhances their Bloodworms with vitamins whereas Tetra does nothing to them.  Personally, I wouldn’t recommend all of their products (flakes/pellets) but I do use Hikari’s Daphnia, Bloodworms and their sinking wafers amongst other things.

  • Hikari
  • New Era
  • Elive

The Best Fish Foods:

There are two brands of fish food that I’m comfortable saying all of their products are of the highest-quality and will readily try any of their foods. Those brands are New Life Spectrum and Omega One. These foods are significantly more expensive but you get what you pay for, they are made with the highest-quality ingredients like whole krill, whole fish, garlic, kelp, different seaweeds, different algaes and a plethora of vitamins. I use numerous pellets from New Life Spectrum. The Betta formula, Cichild formula, small fish formula, the medicated Hex Shield pellets and many more. These pellets are devoured by all of my fish, help keep them happy and healthy and they do not cloud or dirty the tank in anyway. I also use Omega One’s community flakes, veggie rounds and their Betta pellets. You can’t go wrong with either of these brands.

Now that we’ve gone over which specific brands of food you should buy, let’s talk about the basics of what to feed different types of fish.

Your Average Community Fish:

Many people have kept your common community fish at one point or another, these include but are not limited to, many Tetras, Angels, Barbs, Guppies, Mollies, Platies, Danios, Gouramis, Rasboras, Swordtails, etc. These fish usually aren’t particularly picky about what they eat and for the most part they’re omnivores. A good staple food is something like Omega One Tropical Flakes or New Life Spectrum Community Fish Formula. This diet should be supplemented with treats such as Hikari’s freeze-dried Bloodworms and Daphnia.

Bottom Feeders:

Things like Corydoras catfish, Otocinclus catfish and various plecos are often bought to act as a clean-up crew. However, it’s still very important to supplement their diet. My two favorite foods to feed my Sterbai cories and my plecos are Omega One Veggie Rounds and Hikari Sinking Wafers.


Often times people are more concerned about what their Cichilds eat than other fish for some reason. It will depend on the specific fish you keep but I keep Rams and Appistogrammas and I feed them primarily New Life Spectrum Cichild Formula.  I supplement that diet with a variety of other foods including Hikari’s Bloodworms and Daphnia.


Discus are very expensive fish so I see absolutely no reason to feed them anything but the best, New Life Spectrum Discus Formula or Omega One Discus Pellets. I’ve heard stories where people’s Discus didn’t like these pellets but what I usually find is the Discus are used to eating live and/or frozen foods which are obviously more appealing than pellets regardless of the brand.


While I don’t have any personal experience feeding Goldfish or Koi, if I had Goldfish or Koi I would feed them New Life Spectrum Goldfish Formula or Koi Formula. Goldfish and Koi require less protein and fats and more ash content and veggie matter than your average fish. I’ve also heard great things about Hikari’s Goldfish and Koi food but the ingredients used in New Life Spectrum’s foods look to be higher quality.


I do however have plenty of experience with Bettas, personally, I prefer New Life Spectrum Betta Formula. If you prefer flakes, Omega One Betta Buffet is a good option. I’ve also used Hikari’s formula, I found that the colors and activity level in my Bettas increased when I switched to New Life Spectrum’s Betta Formula from Hikari’s.

Fry/Juvenile Fish:

There a few different foods on the market specifically made for fry, my favorite is New Life Spectrum Fry Starter which is an almost dust-like food that’s high in proteins, fats and vitamins to promote healthy growth. A cheaper, easier to find option, would be Hikari First Bites. While still effective the ingredient list isn’t quite as impressive as New Life Spectrum’s though.

As your fish get a little bit older, I recommend using New Life Spectrum Grow. This is a 0.5mm pellet designed to promote rapid, healthy growth in all sorts of fish. This is also hormone-free.

Soaking Food in Garlic – Good or Bad?

Absolutely a good thing, some studies have shown garlic extract helps combat internal parasites. While I’m not confident in that, I am confident in saying that garlic is a natural immune system booster which will help keep your fish healthy. They also love the taste of it. There are easy DIY methods that are cheaper but I’m not allowed in my kitchen so I use Seachem Garlic Guard. Personally I try to do this at least once per week, sometimes two or three times.

Medicated Foods:

The only two medicated foods I’ve used are New Life Spectrum’s Hex Shield (internal parasites/bloat) and Ick Shield. Both of these are great, I’ve used them multiple times with success. Ick Shield is also the only medicine on the market that I’ve ever heard of that disrupts ich during it’s most dangerous stage, the trophont stage. If you want to learn more about ich, click here!

Final Thoughts:

It’s impossible to cover every single food option for every single fish but I hope that this article not only serves as a guide as to which companies make the best food but it also helps teach you how to read the ingredient list at the pet store and make your own decision as to whether you should buy that food or not. Feel free to message me on Facebook if you want my opinion on a specific food!
