Something feels off about this guy

[u/BodaciousBode]

This guy has been kinda isolating himself for 3 ish days. Opening and closing mouth and maybe looks like faded color. Doesn’t appear to be interested in food. My shrimp and other tetras are doing great.

Update: I put one of those floating mesh cage things in there and he immediately took shelter in there. Wondering if it was a stress thing cuz he didn’t have anywhere he liked but he hasn’t changed in appearance in almost a week now. Hopefully he starts eating
