Common name: Sand lizardfish

General information

The Clearfin Lizardfish, scientifically known as Synodus dermatogenys, is a predatory fish species found in coral reef environments. It is known for its elongated body, cryptic coloration, and distinctive clear fins that lack pigmentation, which is a characteristic that gives this species its common name. The Clearfin Lizardfish is an ambush predator, lying in wait for unsuspecting prey such as small fish and crustaceans.

Care

In the aquarium, Synodus dermatogenys requires a sandy substrate to mimic its natural habitat where it can bury itself and ambush prey. This species is not suitable for reef tanks with small fish or ornamental shrimp, as it will likely prey on them. A larger fish-only or predator tank with plenty of hiding spots and open sand areas is ideal. They are carnivorous and should be fed a diet of meaty foods like shrimp, squid, and appropriate-sized fish.

Reproduction

In the wild, Clearfin Lizardfish are thought to spawn pelagic eggs that develop into planktonic larvae. There is little information available on their breeding behavior in home aquariums, and captive breeding is not common.

Habitat

Synodus dermatogenys is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands, north to southern Japan, and south to Australia. They inhabit coral reefs and sandy areas adjacent to reefs, often seen partially buried in the sand waiting to ambush prey. They can be found at depths ranging from shallow waters to about 60 meters.
