[MichaelRobinson]

Hi, I have a baby oscar about 3" that has a couple of protrusions on its mouth. please help identify.

ammonia 0 nitrite 0 nitrate <5. 55 gallon tank two filters about 600-700 gph ALSO, the mouth looks deformed in general?

It could be a wound or it could be anchor worm. Although the lower jaw looks like an underbite deformity.

it has been like this for two weeks, the water parameters are perfect, and it isnt going away. Nor is it spreading.

If it is 2 weeks, then it is not a wound. Who are the other tank mates?

How did you cycle the tank?
