My three angels died. :barf:What would cause them to die? I was treating tank for what looked like the onset of ick. The angels didn't show signs of ick but the other fish had the white spots; Platys, barbs, black shark. they are small silver dollar size and a black angel was smaller. the black was the last to go i found him stuck in part of the heater its a circle on top of it.he wasn't near the hot part. i helped him get out and he didn't make it through the night. I was treating with triple sulfa. I have loaches and i think this is safe for them so i use it.
