Surge Dottyback or Blue-barred Dottyback. Pretty rare fish to come by and varying in appearance. It is very active and hard to take picture of so here is one from the net. It is usually cruising in the live rocks all day. The fish does not like cleaner shrimp otherwise peaceful. $20 Location 92120. Please text 619-813-4528.
Edit: Added 2 fuzzy pictures of the fish.
