I have been trying to breed german blue rams for a few months now, and I can get a batch of eggs to hatch at a pretty reasonable size now. However, the fry will usually survive a week before they start to die off, usually at or when I do a water change. I have read pros and cons to putting snails into a tank with fish eggs. Would they eat the eggs or would they help keep the tank and water clean? Also, how would a water change be recommended, as I used atleast 1-2 day aged water for the switch in the fry tank, just cant keep the little guys alive. This is like two questions in one, sorry for any confusion.
