Can I Use Aquarium Salt With Angelfish?

It is safe to add aquarium salt to an angelfish tank. But, as a general rule, adding aquarium salt is not something you should consider as an immediate go-to for angelfish. Add it explicitly for treating illness to ensure the fish heal faster. Also, ensure that you add no salt other than aquarium salt.

Although you can use aquarium salt for your angelfish, it is often something you may not need to do, so before you jump straight to opting for this, be sure to read on to find out more.

Is It Possible To Use Aquarium Salt With Angelfish?

Using aquarium salt in a tank is more than possible, with angelfish being your primary (or only) fish breed. However, it is often not necessary to use it; this is due to the fact that these are freshwater (tropical) fish and do not require salt to survive.

Many will choose this as their go-to disease prevention method and believe it to be the wisest choice, but be sure to use it with discretion.

In some cases, especially if it is overused, people have found that it causes more issues than fixes regarding the care of your angelfish. And that keeping them alive in a salt-rich environment for too long is catastrophic.

Another point we shall touch on in greater detail is that it is best to try and avoid using aquarium salt in your main tank.

In some cases, and we shall get into this further, you may wind up causing more harm than good for your fish. That said, though, there are instances where it is called for, and this post will break it all down for you.

On a good side note, though, one valuable thing about aquarium salt is that it does not contain additional chemicals, unlike many other products. These could be unsafe for your angelfish and potentially the other members within the tank.

How Can Aquarium Salt Aid Ill Angelfish?

One key aspect of their care is to be aware that angelfish do not thrive in environments with high salt consistencies but are salt-tolerant. You can add aquarium salt, but the dosage amount must not be too high a concentration.

This is where we need to make it quite clear, aquarium salt is designed to help fish to heal more rapidly and is an effective form of treatment.

So, it is safe to use in their tank. In truth, when other remedies are not working effectively, aquarium salt is your best go-to so that you can remedy any problems your fish are facing.

We shall break down some good reasons for using aquarium salt soon.

Still, a simple example is one where your angelfish are enduring parasitic infestation. You can pick up on this by examining that their waste is incredibly stringy and white in hue.

You may need to jump straight to the use of aquarium salt to heal your fish before they become too ill.

Also, be aware that you do not need to only use it in isolation; things, such as medicated food, can also be added toward helping to resolve the issue. The points listed below are some reasons you may need to consider using aquarium salt:

  • Parasites (as mentioned) can be a devastating problem, and you can prevent things such as flukes and ich with aquarium salt.
  • During nitrogen cycles in either new or existing tanks, aquarium salt may be used to mitigate any possible intake of potentially lethal nitrates.
  • Suppose your angelfish (especially in a tank with others that nip) has torn fins. In that case, aquarium salt will aid the fish’s ability to produce a slimy coat that speeds up recovery and helps prevent infections.
  • It can aid the functionality of the angelfish gills by reducing the amount of water intake, leading to less stress on the kidneys.

Using Aquarium Salt In Your Angelfish Primary Tank Or Not

One rule you should consider taking quite seriously and employ, if possible, is to not add the aquarium salt into your main tank unless all your angelfish have been affected by the issue. Instead, remove the sick or injured fish and transfer them into a “hospital tank,” to which you will add the salt.

This tank is reserved for the sole purpose of quarantining and treating ill, infected, or injured fish. This will ensure that the other fish (who do not need to be exposed to the salt) can remain in their normal habitat (which will go unaltered).

Prepare the tank in advance and then transfer the sick fish for the required period until they are fit to be returned to their main tank.

By separating the fish in this manner, you will have greater control over the elements such as ensuring that only the fish that require special food (for example) will be eating it and not have to compete with the others who may be healthy.

Another reason for splitting your fish up is that the high salt concentration can shut down the angelfish kidneys.

Additionally, it hinders the growth of healthy angelfish, aquatic plant life and other members of the main tank. Exposing your healthy angelfish to salt unnecessarily can cause them to become immune to its treatment.

On top of all this, follow the advice and instructions that come with the aquarium salt you purchase. Please do not use more than they prescribe as you may feel it will speed up the process, for example.

If Adding Salt For Your Angelfish, Must It Be Aquarium Salt?

Yes, yes, and yes again. The only type of salt you can add to your freshwater tank is aquarium salt, purposed explicitly for the treatment of fish.

You cannot use other salts, such as simple table salt or any type of salt that you feel ought to have the same qualities and therefore do the same job.

This may seem like something that is merely common sense. Still, sometimes people cannot afford to purchase the right product and therefore go with the closest alternative, or they are incredibly new to caring for fish. They do not know better (think of it like the different types of oils for varying vehicle types).

You ought to be able to source aquarium salt from your local pet or fish shop or even order it online. Just make sure that it is the sort that is specific to your needs.

Once you have added it to the hospital tank, you are ready to transfer your fish. Maintain an eye on your angelfish, though, as sometimes certain fish react negatively to the salt and need to be returned to their primary tank.

Also, remember, this is not used for general maintenance but is intended to be beneficial for your freshwater angelfish, which are ill or in desperate need of treatment. It is for when you require a solid solution to the problem at hand.


Angelfish are glorious fish and splendor to watch. These fish are also typically easy to care for as they are hardy (even though they appear delicate). The likelihood of them falling ill is typically quite slim. However, this does not mean they are immune and cannot fall prey to parasites and other health problems. So, in these instances, using aquarium salt can and sometimes needs to be done.
