I would argue against no water changes for a month. Just recently I lost A LOT of ram's fry because I did not change water in their tank (2g) for a week. All of them died in just few hours and deaths stoped after change. I have only few left, but already have several new batches and defenitely will try not to do same mistakes again. Apisto's fry is much more hardy and I did not have any fry deaths in a batch of about 70 fry, although I sometimes skip water changes for them. I would also speculate that the original problem was not with water maybe, but with fry starving. Lilia > I've had success with no water changes at all for up to a month.
