hi dominic, I've never had any problems doing water changes with fry in the tank. I even do them with eggs in there too. Just take a little time and make sure there isn't a difference in temp. Also, I usually cut the percentage in half, and up the frequency. for the 1st 2 weeks or so. Rich dominic stones wrote: > > Yaaaaayy! > > I've finally succeeded with my Apistogramma sp. cf pulchra!
