Overnight, my gourami suffering from dropsy died, i was expecting it. But my serpae, i didnt notice problems until last night, and before i could do anything, it is dead with the gouarmi. It isnt dropsy. I dont know what it is, but it doesnt look pretty... It looks like there is an open sore on the one side, last night he had trouble staying normal. His tail would float up so he was almost standing on his nose, then he would correct, and float back again.
