Hi guys, this happen so suddenly and my guppy looks like it's dying. So I'm having a 9G tank with 6 neon, 5 guppy (2male3female), and 3 Platy(2male1female). Just now I discover that my guppy has deformed bone, it looks like it's dying but it's still swimming. I just putted melafix, hope it will help. My question is will it get better? Will it affect the other fishes? And any advice what I should do? I just saperated her in a net since I don't have other tank.. Please help...ammo: 0ppm no2: 0ppm No3: 10ppm ph: 7.0 PS: Sorry for bad English..
