I had 5 Guppys and 2 old fry & 1 new fry & 2 red and blue neon, 1 black neon and 1 silver neon last night, but i went away for a night and i feed them there usuall when i came back i found my female guppy floating around the top of my 5g tank, I got my brother to take it out. Just after i found it i realized i hadn't seen my male guppy(beuty) well i found it lieing a the bottom of my tank also gray...
I read that if a neon has a big belly then it is diseased and will kill all the fish with it. well my neons had a big belly.
I am wondering if this is true about the belly and if any1 can give me advice
