Ok, I was just at Pollys Pets in UC and they have a chromis/damsel in a back tank all by its lonesome that looks pretty cool. Luckily, its not for sale yet so I have time to figure out what it is The little guy is shaped like a chromis, including the way the fins are tapered, but is solid black with a yellow tail that goes to transluscent at the tips. There are two wholesalers online that sell a yellowtail black chromis which looks identical to it. However, its a wholesaler so no fish info. The other option is a Yellowtail Dascyllus (Dascyllus punctatus) that is listed on live aquaria who has close to the right colors but the body shape and hue is off (don't know if thats because the picture is of an adult and I'm looking in the store at a juvenille). Any help would be appreciated.
