Triggerfish
Triggerfish can be a interesting choice for your home Aquarium. Mainly due to their unusual swimming style. They can be territorial, so a larger tank with plenty of rocks is a good idea.
Not a good idea keeping them in a invert tank, as there preferred food is squid, krill, small fish, shrimp, clams which they need to graze on to keep there teeth from getting too big.
So bare that in mind.
