PLEASE HELP! I have a dalmation lyretail mollie and just resently he has been laying in a rainbow shape (or an upside down U) at the bottom of the tank....hes not dead but looks like he is. When he tries to swim he swimms in a barrel roll type way or faces down but his tail sticks up and he tries to swim. All his fins are out when hes at the bottom and breaths slowly.
