I bought 5 platies Wednesday. One died 3 hours after getting in the tank (domino platies) but it didn't act right very quickly. They are the first fish to be added to the 46G bowfront. All water parameters tested in normal range. I added 3 female red wagtails yesterday afternoon since the others appeared to be too high ration of males. Last night one of the dominos started acting funny.....laying on the bottom and then swimming very fast through out the tank, then floating to the bottom.....finally dying. No visible marks on the fish. I went ahead and did a 30% water change, although the water tested okay. This morning all seem well. Does anyone have an idea what may have happened to the domino platy? Does the behavoir indicate anything in particular?
