About Sargassum Frogfish
A small, stocky frogfish (family Antennariidae) with a rounded body covered in wart-like tubercles. Coloration varies from yellow to tan to brown, often with darker markings and spots, allowing camouflage in sargassum. The characteristic pectoral fins are arm-like and used for "walking" across surfaces, and a modified dorsal spine functions as a fishing lure (illicium).
Key facts
- Diet Details
- In captivity, feed small live copepods, amphipods, and other tiny crustaceans. Juveniles require rotifers and newly hatched brine shrimp. Some individuals may eventually accept small frozen foods or mysis shrimp, but live foods are strongly preferred and essential for newly captured specimens.
