The flounder is likely wild caught out of the Carribean. Flounders are veracious predetors. Offer live foods such as ghost shrimp until it can be weaned onto krill and the like.
Cool. He is about three inches long and all my shrimp are doing fine. I recently notice my maroon clown is messed up. One of the bottom fins looks like it has been chewed on. He also has a white line across his side fin, and he has a white thing stuck to his side near his shoulder. I have pics and will post soon.
