I have hed my 10 gallon tank for a while now and i have 1 friendly betta, 1 small pleco, 5 neon tetras, 1 black neon tetra, and 3 white clouds. So when i got the white clouds they looked fine but a few days later one of them looked bloated. I knew i was feeding them right because the other fish were not bloated. So i assumed she was pregnant(and the other 2 were males). Its been months and she is still really bloated. Does any one have a clue to what is going on here?
