Alan - Now THAT!!! is creative - good idea. Thank you Jonathon for your input! I didn't think it would be overly harmful. Nice to know those little buggers can essentially keep the water clean? I think part of the problem is not getting the excess food off the bottom when doing the water change - they have gravel on the bottom ( I prefer my pairs in natural environment and I simply removed the parents once they were wigglers) and because of the gravel, I can't see them very well, don't want to suck them up. I have a very strong light on them and was slightly over feeding the parents because the male is old and blind - I wanted to make sure he could find the food. This is what started that darn diatom bloom I think. They were breeding in the diatom bloom.
Usually I suck out the babies with a turkey baster and put them in a clear bottom tank - but when it came time this time around - I couldn't find where the parents hid them - so I pulled the parents. Babies are very happy playing in the moss and eating liqui-fresh for now.
