so, one of my kissers died on saturday. and the other one (which is in his own tank) is covered in little white dots. i've been treating him and the others with ick treatment (it's blue). he's just been laying around at the bottom of the tank. he eats and occasionally moves, but isn't very active anymore. the betta i got is also hanging out at the bottom and has a white mark on his head. there are no other signs of illness on the betta. the gourami i just bought (with all the others) is doing just fine as is my origional gourami. what's going on here?!
