The Sargassum Fish is a member of the Antennariidae family. With a body of mottled brown and tan, several projections give it more of an ornate rock-like appearance than that of a fish.

A good reef dweller, the Sargassum enjoys perching on coral ledges and requires a tank of at least 30 gallons.

The Sargassum feeds by ambush, lying in wait for an unsuspecting fish or crustacean to go by and then lunging forward, grabbing and swallowing the victim whole. The Sargassum has been known to devour fish nearly equal to its own size.

A diet of feeder fish and shrimp should be provided. Do not overfeed as the Sargassum may stop feeding.

Approximate Purchase Size: Small: 1" to 2"; Medium: 2" to 3"

Customer Testimonials

I've kept one in a 55 gallon tank before, and was completely satisfied. They are a great addition to a tank, and are perfect for small (30) gallon tanks, especially to watch their feeding. A great species for the home aquarium.

by far the most amazing fish in my small predator tank, he will eat anything including a rock so be careful.
