I am wanting a BN pleco, but I have heard he must go in the tank last due to being territorial. This is my current set up: 55 gallon 2 male platy 3 male guppy 1 male molly 10 harlequin rasbora 7 albino cory 1 pearl gourami 1 ghost shrimp My plans are to get one more pearl gourami once this one matures enough to tell if it is male or female. I plan to get more ghost shrimp and another school of 6 fish. I cannot decide what ones to get!!! Can I get. bN pleco now before I get the rest of my fish? Thanks!
