Pls see attached pics. Im not sure what it is and what I need to treat with.
The swallowtail male is with a swallowtail female, yellow tang, kole tang, and snowflake eel in a 50g tank. Its essentially my QT before going to display.
Parameters:
Ammonia - 0
Nitrite - 0
Nitrate - 40
They are all eating well (mysis, flakes, pellets, nori) and earlier today, I mixed food with Selcon.
What else can I do?
One of the pics is of his good eye. Its tough to take iPhone pics of him.
