Bearing in mind that there is another alternative!!! You dont have to go through the expensive of setting up a breeding tank, or the stress of seeing the fry eaten by bigger fish. I used a breeding net to raise my 24 baby mollies and they all lived fine. its easier if you keep the mother in there before she gives birth and take her out after. I fed mine on Liquifry Food for Baby Livebearers. The mother shouldnt have this! after about 2 weeks I started feeding the normal flakes too and then took away the Liquifry gradually. Now they are about a month old and I have 5 left, I gave the rest to my local lfs. They are still in the net and doing fine!
