Hi We have finally gotten our tank cycling, all the levels are good. It's DD (8yrs) tank, and so she picked out the colored gravel that they sell for the substrate. Well not we have tried putting in some live plants (moneywort) and am having a difficult time getting it to stay at the bottom. So is not the best stuff to use?

In addition, there were 3 some Corydoras and now the 2nd albino doesn't seem to be feeling great. The first albino that died, we thought maybe it hadn't recovered from being in the betta tank even though it had been moved for 2 weeks. Now this albino is hiding in the bottom/back of the tank and when disturbed swims a little funny. The other Cory (I think its a green) is swimming around fine. Could the substrate be the problem?

Um also she has a black molly (F), dalmation molly (M), cremecicle lyretail (F), red wag platy (F), blackskirt tetra (F) in a 10 gallon tank. How do you keep from being over run by baby fishes? Do you just occationally use the breeder tank and let the other fish eat the babies when you don't want them? What do you do with the babies?

Thanks so very much
