Care

Diamond Lizardfish require a specific set of conditions to thrive in captivity. They are best suited for larger aquariums with plenty of open sand areas for burrowing and hiding. These fish are carnivorous and require a diet of meaty foods such as small fish, shrimp, and squid. It is important to note that they may prey on smaller tank mates, so they should be housed with similarly sized or larger fish.

Reproduction

Little is known about the reproductive habits of Diamond Lizardfish in the wild or in captivity. They are not commonly bred in home aquariums, and most specimens are wild-caught.

Habitat

In the wild, Synodus doaki is typically found in sandy or rubble substrates near coral reefs. They are adept at camouflaging themselves within their environment to ambush prey. Their natural range extends across the Indo-Pacific region, from the Red Sea to South Africa and east to the Society Islands, north to southern Japan, and south to Australia and New Caledonia.
