Another great staple food includes lettuce, spinach, and brine shrimp.

You also need standard filtering equipment installed. Remember that this fish is a great jumper.
Secure the top of the tank with safety lid and also breathable material.
Even though it is a good idea to bring some friends over, you have to consider the aggressiveness.
A rainbow fish should not be paired with the other “shark” species, as they will attack each other.
You are only allowed to do so when you have huge aquarium where each “shark-like” fish could claim its own territory.
A rainbow fish rarely nip or bite its tank mates. In some cases, the red fin shark will chase specific fish non-stop, preventing it to get some food.
