oscar fish introduction

Introduction

This fish is very intelligent, it can even recognize it’s owner. Oscars have they own ideas. If they don´t like how the items are in the aquarium, they pick them up and replace them, or they spit it out from the tank. It doesn’t matter if the plant or rock is real or plastic. If you have a high aquarium, standing near it can be dangerous. The best choice is to have a sand bottom and few big rocks in the tank. Sometimes Oscars pretend that they are dead. In nature they pretend to be dead and wait until a small fish comes close so it can be caught and eaten.

Oscars are aggressive fish so they need a big aquarium and a large group, because if there are only few fish they will fight, and the weaker Oscar will feel miserable. The best solution is to have either one or many (6 is the minimum) Oscars, but never only a few. I have heard that sometimes three fish get on well, but usually they fight and attack each other without apparent reason. But even if you have more of them in one tank, when they grow up a male and female may separate from the group and start to defend a part of the tank, in which case it is better to remove them.
