Breeding. I'm going to start when I move into my new house, and use my 30 gallon as a growout. However, before I even think of doing this, I am having some problems with my fish. Mainly with my CT's, I'm not seeing any poop. I have a good feeling they are constipated. Now, I've tried using the pea technique, still nothing. When I first got them, I saw black, big poop. Now, if anything, I see something that looks like cotton. Anyone have any ideas? Should I put them in bettamax? Starve them?
