Hi
I have 5 datnoids in my 100 gallon tank, with some cichlids and clown loaches. Ihave them in my tank for about 3 weeks now. They eat well mostly live guppies. This morning I found one floating all over the show, half dead. The mouth and gills were still moving, so I put it in a net in the water so the other fish don't mess with it but it died half and hour later. I did a water change yesterday, and all my other fish are fine. It also did not have any spots or bite marks. Any ideas or reasons that could have this
