Now I'm down to 3 Guppies in my 10g tank. Pretty sure its fin rot thats killing them. I am treating the tank with medication but looks like probably at least one more is going to die. This makes me very sad...I hope the last 2 will make it...one of them I have had since she was born. Wish I could put the last 2 in my 70g, but don't want to spread disease to my Rams. :sad:
