Panther Grouper (Cromileptis altivelis)
The Panther Grouper, also known as Polka Dot Grouper, Humpback Grouper, High Finned Grouper, or Barramundi Cod, is a large marine fish that can grow up to 28 inches in length. It has a distinctive appearance with a thin vertical profile, substantial height, a small head, and an elongated snout giving it a humpback look.
Adults display a cream-colored body with black spots scattered across the body and fins. The upper part of the fish is narrower than the base, and the head has a concave profile at the base.
This species is typically found in lagoons, seaward reefs, silty areas, and coral reefs in the wild. To replicate its natural habitat in an aquarium, use a sandy substrate at the bottom.

The Panther Grouper is a striking addition to my marine tank. It has a unique humpback shape and the black spots on its body stand out well against the cream color. I’ve maintained it for over six months and it’s very active, though it does need a large tank. The sandy substrate matches its natural environment perfectly.

This fish looks impressive and fits well in my 120-gallon reef tank. The coloration is vibrant and it’s peaceful in its behavior. I did have to adjust the sand depth to ensure it could dig, which was a small effort worth it.

I was initially skeptical about keeping such a large fish, but the Panther Grouper has adapted well. It’s active but not aggressive. The black spots are clearly visible and add a nice contrast to the tank’s overall look.
