What kind of fish can you keep with an axolotl ?

You may have one or more axolotls and you want a little more animation in the Tank by adding a few fish but you wonder is it really possible to make axolotls cohabit with other freshwater fish ?

Yes, you can introduce other species of freshwater fish in the tank of your axolotls if it is large enough of course but you have to respect these conditions to start:

  • They must not be numerous (less than 10). 
  • They should never be bigger, or even the same size with your Axies.  
  • You must have an excellent filter and change the tank water more frequently. 
  • And finally, you must permanently supply your tank with these small fish, because they will surely be used as food for your axolotls. 

Keep reading, there are other precautions to take before introducing these fish into the Tank of your axolotls. 

Which fish can you coexist with an axolotl?

Try to introduce fish of less than 4 cm if your axolotl is an adult of course and measures a little more than 15 cm, the principle to be respected here is that the fish must be able to pass easily in its mouth. 

They must also be nutritious, so I recommend White cloud minnows, Killifish, Guppies, Mosquitofish, endlers or charales (very typical in Mexico) and if you don’t find these species in your pet store, you can use Goldfish

What are the precautions to take before introducing these small fish into an Axie’s Tank?

In addition to the precautions I mentioned above, you must first of all choose small fish, which are neither sick nor carrying parasites.

You will buy about ten of them and put them in a small aquarium or tank and quarantine them for at least a week to make sure they are safe for your axolotls.

You will introduce them into the aquarium in broad daylight and you must especially monitor more closely what happens in the Tank during the first week.

If you see that the small fish to attack the gills of your axolotls, and they do not react by chasing them away, you must remove these fish immediately.

Yes, you will soon notice that one or two small fishes are missing in the tank, the axolotls have probably chased them and eaten them.

What you are going to do now is to wait for the axolotl to drop a turd, you are going to pick it up with a Turkey Baster for example and crush it. If all goes well, you will find traces of fish bones in it, a sign that your axolotl has digested the little fish well.

What other species can you co-exist with an axolotl?

If you want neighbors that your axolotls won’t hunt, in any case they will try but they won’t always succeed, I recommend fresh water ghost shrimps or fresh water snails that can stand the cold if you can find some…

A freshwater shrimp like Ghost shrimp : they tolerate cooler temperatures, they will also clean the bottom of the aquarium from food remains and maybe serve as food for your axolotls even if they are not easy to catch.

Fancy shrimp and Cherry shrimp are very nice but they need a bit higher temperatures, you can try them too.

Is there a risk if you introduce too many fish to live with an Ambystoma Mexicanum ?

Yes, in the long run, because these fish may probably end up stressing your axolotls, that’s why you should never put more than 10 at a time.

There is also their urine and waste and the remains of their food which could increase the PH of the water and make your axolotl sick, not to mention the risk of aggression, a small fish could still manage to thwart the vigilance of your axolotl and tear off a piece of its gills.

Can axolotls eat Goldfish ?

can goldfish live with axolotls ?

Yes, axolotls can eat goldfish, goldfish is not the fish that axolotls like to eat the most, but they will be able to eat it anyway.

This fish can also live in cold water, you can introduce it into your axolotl’s aquarium but it will have to be very large, almost twice the width of your axolotl’s mouth, otherwise it will surely attack it and swallow it, and this will happen at night when your Goldfish is sleeping and your axolotl is in hunting mode.

How to have an axolotl and a Goldfish live together?

Yes it is possible, it is always possible but I have never tried it before and I do not guarantee the success of this operation but I do not discourage you to try

What do you have to lose!! it’s just one more meal for your axolotl in case the operation is a failure!!

How to keep my guinea pig Healthy and Happy ?

To keep a goldfish and an axolotl together, you will need a large tank with a good silent filter, water that does not drop below 65°F, otherwise your goldfish will become torpid and die from the cold.

Don’t forget that Goldfish can also attack the gills of your axolotl and it will have to kill the car fish just to defend itself or for the territory if the tank is too small.

Can Axolotls eat Betta fish ?

is betta fish a good tank mate for an axolotl ?

First of all, you should know that the Betta needs warmer water (75-80°F) than the axolotl (60-64°F), so you can’t have them living together for long.

On the other hand, bettafish are aggressive and territorial fish, which will surely attack the axolotl and its gills when the axolotl is small.

For a large axolotl, the bettafish is just a live meal, which it will probably eat one night when your betta fish has gone to bed.

Axolotls eat betta fish that can pass through their mouths


Finally, let me tell you the two species of freshwater fish that you should never introduce in the tank of your axolotls, they are the tilapia and the carp.

These two fish are natural predators of axolotls, so avoid making this mistake !

You should know too that younger axolotls may nip each other’s feet and gills if they have no enough space or shelters . Even axolotls up to (5 or 6 inches) may nip their tank mates, occasionally inflicting serious damage , that’s why we recommend a large tanks .
