I just realized that I have two baby platys in my tank, and the tank is due for a partial water change tomorrow (I do a partial every week). Is it ok to do the water change with the babies in there? I haven't seperated them from the tank because they've made it this far, they are about 1/2 in. long. Just didn't know if the change of water would kill them, or if it's worse to not do the change? What do you all think? Kathy
