Please help my trigger!!

[Chappy8]

I have had my huma huma trigger in my tank for about 5 months now. Two weeks ago I decided to add a miniatus grouper. They fought for a little before the grouper scratched the trigger with his mouth on the triggers nose. A week after this, a lump has occured on the triggers nose. The lump has remained now for a week. The trigger has become less aggresive when eatting and swimming. I don't know if this is the cause of the groupers dominance or the lump. Can anyone tell me what this lump is and what I can do to solve this problem? Thanks for your time. (The lump is under the skin and is about the size of a dime. My trigger is about 4 1/2 inches .)

I thought this was weird, since I had a miniatus grouper and a picasso trigger in a tank together for about the same amount of time with no problems at all, even during feeding time. They were the only two fish in the tank. What size tank do you have them in? You may want to put the trigger into a med tank so you can treat it. At 4.5", I think it should be fine in a 20 gallon for a few weeks. Good luck.

Peace,
