Well i have had these baby mollies since they were fry in my other tank. They were always doing great, very active, would beg to be fed all day long, etc.. Well last night i did a small water change, added some dechlor, everything was great. Well today i turn my light on take a shower come out to feed them and noticed 3 of them are stuck in the intake filter, and 2 are upside down on the bottom of tank in the java moss. I trapped them all and put them in alittle breeder cage thing to observe them. Could this deal with the fact that mollies prefer salt? Im clueless to why they just all the sudden start dying. I tested the water and everything is normal as its always been. Any suggestions?
