Sorry ..ammonia 0, trites 0 and trates are 5. This is on an api master test. I did a 10 gallon water change yesterday. The only thing I've done this morning besides test was a little lemon juice for a majano. I tested after. The fish had a little jagged tail and under blue light it looked like it's tail was peeling. Both clowns had way appeared to be a fungal/bacterial growth on their bottom lips. I read good water parameter would clear that up and it wasn't really dangerous. The other 3 fish in the tank are swimming around normally.
