My brother and I just started up a 30 gal tank we had seven fish, two midnight black mollies, Two spotted platys, two red platys, and a catfish. Recently, our tank was riddled with ICK, we have corrected the problem but lost most of the fish. We currently have two red platys and the catfish left,the platy are both male. And I wanted to add females to the tank so that they were not so lonely. We have plants (plastic and real) so there are places for them to hide in. Just needing to know how soon can I get the females for this tank.
