HUGE bump on flowerhorn

[amv123]

My flowerhorn has a large red bump on his side. It appears to be under the scale and had been there a couple days. I have added salt and coppersafe in case it is a parasite. Anybody know what it may be or what to do?

any ideas?

bump is still exactly how it looks in the picture after two days

It's probably an ulcer- or he ran into something...

Do a water change, re-salt, and bump the heat up..

Should be fine.

And forget the copper.

What's the temperature currently?
Water parameters?
