Yellow Damsel

[miweinstein]

I purchased 2-yellow damsel fish from saltwaterfish.com. They arrived today.
One of the fish has a black circle with an inner circle on its tail fin...resembles an eyeball!
Does this indicate a sick fish and should I remove it from the tank?
Thanks for any input.

Not to worry. This is normal coloration for the Yellow damsel. These fish have two dark patches-- one on the base of the tail and the other on the middle of the dorsal fin.
If you're not seeing the "patch" on the dorsal, it is because the fish is a juvenile.
