From the above data of the 2 freshwater fish, you will notice that their living conditions are almost the same, and even their temperaments are almost alike.

So can they truly coexist? The answer is yes! although they might be having small problems like the shark chasing the Oscar all over the tank and fin nipping etc.

But from experience, Rainbow sharks don’t normally disturb other fish as such, unless the water condition or tank is not suitable for them, thereby breeding aggression in them.

So when keeping a rainbow fish, try to get a large tank like 55g, but once you want to keep a mate with it, then 75g and above is the ideal, depending on the size of the fish.

Also try to keep hiding/resting places like caves, vegetation etc in their tank, so that they won’t get stressed easily which may lead to aggression.
