I've noticed 2 of my guppies with fin rot even though I've been changing water liek twice week. They had a huge water change last Saturday because thats when I transferred them from the 10g to the 20g. I only used 1 bucket of old water in the new tank but I am using the old filter with media. My question is...I have 7 one week old fry in a floating breeder in the 20g, if I treat with melafix & pimafix would it affect them in any way? I dont have a big enough tank to take the two out and treat and besides I want to treat the whole tank because I notices a split in the fin of a sword too.
