Fungus infections are very difficult to treat and are usually secondary invaders resulting from an injury on the fish or recent wounds from parasites or bacterial infection. Once the fungus starts growing on the fish, it usually continues to grow and enlarge. Unless medication is provided, death results.

Special note on Maracyn Oxy: Fritz Maracyn Oxy has been shown to be effective against certain gram-negative and gram-positive bacteria.

Maracyn Oxy can be used to treat fish exhibiting the following symptoms: clamped fins, swollen eyes, heavy or rapid breathing, patchy coloration, or any change in the behavior of the fish. All suspected bacterial infections should be treated immediately.

If irritation persists, get medical attention. For eyes, flood with plenty of water and call a physician immediately. Internal antidote: Drink large quantities of milk. Call physician.
