Yes, a yellowish gray with black stripes. I'll post a pic later. I originally figured he was stressed, but I can't figure out for the life of me why he would be...especially since he isn't hiding. I'm thinking of putting him in the frag tank, but I didn't want to separate him from his shrimp. We bought them together as a pair about 8 months ago. He's never left the shrimp until now. Maybe they had a fight.
Do you think I should separate them (especially since he isn't even watching the hole) and put him in the frag tank?
Thanks for getting back so fast.
