This is a great product for Mollies since they are susceptable to fungi - I just put it in when I change the water out no matter what. It can't hurt! I bought this product the first time when I has some kind of white fungi attach itself to all my fish - lcear it up in a couple of days with no casualties!

Pros: good product

Cons: none

Not the first item you think of purchasing for your fdish, but it should be! Fungus can be fatal. Protect your fish!!

Pros: Easy to use and necessary

Cons: None known

Fish fungus is very common. But it's great to have a product out that can help fight against it. I know I don't like touching or cleaning fungus out of the tank.

Pros: it's healthy

Cons: it's smells
