Comments: These are highly active and intelligent fish. They enjoy a planted tank to explore and engage in. Unlike most members of it's family, this tetraodontid displays an unusual amount of tolerance towards other fish. However, they may still be  e to nipping fins; thusly, fast moving, inconspicuously finned tankmates are ideal (such as large tetras). Unless they are being fed a daily supply of snails, their teeth will need trimmed every 4-6 months.
