So I've had a heck of a time setting up, my first atempt was an absolute failure . But after much deliberation and research , I have it set up once again an running it threw its cycle just the other day I bought 2 platys , male and female who at this point seem to be doing just fine they have found many hiding spots and follow oneanother everywhere, and are quite active ..... Shouldn't they be working up an apitite. I have had them in there for about 3 days , feeding them a pinch of fish flakes every day, when they are active. But to no prevail they seem to be more interested in themselves than eating. I even tried other foods like freeze dried brine shrimp and tetra min flakes, in addition to the flakes I started with. Is this normal ?????
