This fish has been in my tank about 4 months now and came in with a purchase of 4 SAE's. Initially, all four looked identical but he's since developed a separate look and personality.
He's
incredibly hard to photograph as he's hiding at even the slightest sign of movement outside of the tank so I had to bait him with food and wait about 25 minutes for even this photograph. The other three SAE's are normal happy-go-lucky SAE's.
Any help with an ID?
