Pearl gourami red bumps on face

[Vineheart01]

While watching my fish I thought one of my pearl gouramis was holding something in its mouth. After awhile I noticed it was more like a red bump on its lips

Only fish in the tank doing this.

7.0 pH 78.8F tank that's mildly hard water.
There's a redtail shark, bristlenose pleco, tigerbarbs, snails, congotetras, and 2 other pearls in the tank.

Difficult to get a pic right now since I recently fed them and theyre highly active but ithink I got a clear enough pic

That appears to be an infection on his lip most likely from a wound. The fish would be best treated with an antibiotic in a hospital tank. With a pH of 7.0, a combination of Kanaplex and nitrofurazone is what I recommend.
If you need help setting up a hospital tank, my post here: Quarantine tanks and Hospital tanks, are they really different? explains how to properly set up a hospital tank in post #2

Hope this helps.

Just to correct my last post, that's a female, not a male.
