The Popeye Catalufa is a striking addition to my 75-gallon reef tank. It’s peaceful and has vibrant Sumatra coloring. I’ve observed it coexisting with other non-aggressive fish without issues. It’s a bit shy at first but settles into the tank after a few weeks.

I added this fish to my intermediate reef setup. It’s active but not aggressive. The coloration is bold and stands out. I keep an eye on it near soft corals, as the manual suggests caution. Overall, a good choice for a colorful, calm addition.

After a month, the fish has grown steadily and looks healthy. It doesn’t chase other fish and stays in the middle of the tank. The Sumatra coloration is vivid and very attractive. I’m happy with the purchase.
