Care

Humpback Snappers require a spacious aquarium with plenty of hiding places, as they are naturally reclusive during the day. They are carnivorous, feeding on a diet of small fish and invertebrates in the wild, so in captivity, they should be provided with a variety of meaty foods such as shrimp, squid, and marine fish flesh. Care should be taken to ensure that smaller tank mates are not at risk of predation.

Reproduction

In the wild, Humpback Snappers spawn in groups, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting with currents until they mature. Reproduction in the home aquarium is rare and not well documented.

Habitat

Myripristis pralinia is typically found in coral reef environments, often in association with caves and overhangs. They are nocturnal, venturing out at night to feed. Their natural range extends across the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean.
