I fear I may lose one of my true parrots. He's one of my favorite fish and has always done really well til a couple weeks ago. He's already pushing 7" and I've only had him for about 6 months.
I noticed what looked like a splinter on his lower jaw. It is coming out of what I would describe as a pore. It almost seems similar to when a human gets an ingrown hair. It has been knocked off a couple times in the last couple weeks but then in a day or two it's back. It's red in color. He has acted fine throughout until last night when he started hiding and quit eating. Do you have any idea what it could be or how I could treat it? Here's some pics. I appreciate any advice you may have.
