How Many Rainbow Sharks Can I Have?

As I have explained many times above that Rainbow shark does not tolerate each other and could hardly live with other too, you might begin to wonder if you could be able to keep some of them, and how many could be okay for you to keep.

How many rainbow sharks can I have? You can have as much of rainbow sharks as you want, but for the fact you keep them in a very huge tank or you keep them in separate tanks that are up to 50 gallon each.

Although being aggressive and territorial, what they really need is enough space, I mean a very large or huge space and hiding places like caves, pipes, substrates and plants.

Provide such for them and they will be busy with it and mind their individual territories, thereby making it possible for a sustainable peace in the tank.

Once they have enough space, each of them will have to mind it’s territory and keep to it.

So with a very large tank and with hiding places in the tank, you can keep as many as you want, but if you ask me, keeping only 6-9 and especially more female in a 450-500 gallon tank or maybe with other suitable tank mates is cool.
