Is it ick? fungus?

Its a P knob.. usually appears when Ps bump, attack, or rub against quarium sides. Can develope anc open sore if continious. Give it time to heal and will disappear in time also

looks like a bump - can you post this pic in the sick fish pics thread pinned in this forum please

 

[Mr. Hannibal]

None, it´s Chin bump, pretty normal when Ps rub against aquarium glass...it will heal as soon it stop rubbing...!

would adding salt help it heal up faster?

its not an open wound, but if he continues rubbing then it could be opened up and lead to another infection. i would add some salt just to be safe.
