Amazing that your orangeheads were successful on the first try in such a busy tank. Mine always lose their wigglers a few days in. Usually dig a pit and drop them then they get carried away by the filter current. I'm going to put them in a tank with only a sponge filter and let them have at it.
You must keep very clean water in there to get all this great coloration, trailer growth, and breeding all with that many fish in there.
