Adrian Lambert –
The Popeye Catalufa is a striking addition to my 75-gallon reef tank. It has a vibrant Sumatra coloration and remains peaceful despite the presence of other fish. I’ve observed it feeding naturally and not showing any aggressive behavior. It’s a great choice for intermediate reef keepers who want a colorful, calm fish.
Jack Cornish –
I bought this fish for my intermediate reef setup. It’s active but not aggressive and has adapted well to the tank environment. The color is vivid and stands out among other species. I do see occasional nibbling on small polyps, so I keep an eye on invertebrates.

This fish has been in my tank for three months now and is thriving. The coloration is intense and the fish is very calm. I appreciate the care level being intermediate—easy to maintain without needing constant attention.
