its only gonna have a max of three fish. get 2 very young fahaka puffers and let them grow up together so maybe aggression will be minimal... and then have a pleco thats bigger than them at first so they should learn to leave it alone.
I hate spoiled kids . . . lol, jk jk. Dang man, I am jealous. Wish my parents were as accepting, lol. It seriously took me 6 years just to convince them to allow me to get a 55 gallon. -.- Century for 300+? Lol. Personally, I would get an Umbee, a show quality beast, and raise him up to his full potential. Then laugh when he charges my little cousins, bwahahaha, lol.
