Red tail sharks are very aggressive when older. They fool many many people into thinking they're perfectly peaceful (borderlands reference) and then when they grow up they attack all their fish and they wonder what's wrong. They need at least 55 gallons each and are aggressive if kept in anything below that mark. 40 gallon breeders will work for 1. Very beautiful fish especially when older! Want one real bad, good luck with them!
