He wasn't in one of the smaller tanks with the hermits and stuff - he was in one of the bottom fish tanks on the right wall of the store. I don't remember seeing the patch on him in the store or in transit. Transit was VERY cold, so he was super stressed out when we got him back to my tank. Did a slow acclimation to bring the water temp in the bag up (from around 65 degrees - teach me not to bring a cooler with me to insulate the little guys) and he seemed to perk up. When I put him in my tank, he immediately darted into the rockwork, and it was the next time that I saw him that he seemed to have the patch on him.
He's in the tank with 3 chromis. They checked each other out a little, and I've seen him out of the rockwork a couple of times hanging out with the chromis, and they aren't really bothering him (that I can see). He doesn't come out much though, and spends most of the time sitting under the rocks like in the photo I posted.
It's really hard to get a good look at the patch because he spends so much time hiding. It doesn't look too bumpy from what I could tell - not like a growth. Looks a little smoother than that at least.
As far as eating goes, I have seen him eat very little. He's nibbled at some algae, and he sort of half-heartedly went after some of the flake food I dropped in the tank. I put in mysis shrimp and he was totally uninterested. I was thinking about feeding some live brine shrimp to see if that might entice him to eat.
So ... more thoughts?
