Fish Fanatic
Hi. I had these beautiful anubious growing in my 20 gal aquarium. Then all of a sudden 5 months ago I get this film on them. I water change 50%/1time week. There are only five fish in the tank. I tried scrapping it off with my fingers. Peroxide . Nothing gets rid of it. I was told it could be the start of Black Beard. But the tell tail black stuff isn't there. I also thought 5 months ago it was a dirty canister filer. Nothing happened. Anyone else have this problem?
