I love my little guppies but my males are taking turns getting bloated, scales almost look like they are standing out, and breathing problems before death. My females seem fine. My Fry are alive and kicken. I am down to 9 guppies (2 male) and a bunch of fry, plus a snail or two-don't know where they came from-and some ghost shrimp in a 20 gal tank. I just moved up 10 gal to the 20 gal and things are not going smooth. Water tests are fine. I am tired of the local pet stores telling me my boys are girls. They are deffinatly male. I have treated with Jungle Fungus, changed water and i don't know what to do. I have had these guys since i was in the 2 gal tank...please help.....bloated males dying
