Hi Redneckgirl! Have you seen the "Care Articles" section yet? Lot's of information here: Frog Forum - Fire-Bellied Toad Care and Breeding - Bombina orientalis and relatives. Although need some answers to narrow cause down; it appears you have a protein/organic film in water related to an immature or out of balance nitrate cycle. Can you please give us more information on your set-up (how old and if you added any bacteria colonies when started) and cleaning procedures to include gravel and filter media? Thank you!
