Sargassum Anglerfish (Histrio histrio)
The Sargassum Anglerfish, Histrio histrio, is an unusual predatory marine fish specially adapted to life among floating mats of Sargassum seaweed. Also known as the Sargassum Frogfish or Sargassumfish, it has an irregular, leaf-like body, branching skin filaments and highly variable mottled colouration that provides exceptional camouflage.
Rather than actively chasing food, this specialist ambush predator uses a modified dorsal spine as a lure before engulfing passing fish and crustaceans with its rapidly expanding mouth. Its distinctive appearance and fascinating hunting behaviour make it highly desirable to experienced marine fishkeepers, but it requires carefully selected tank mates and specialist feeding.

This anglerfish is a striking addition to my marine tank. It blends perfectly into the Sargassum mats and has a fascinating way of hunting. I’ve had it for three months and it’s still active and healthy. Only recommend for experienced aquarists with proper setup.

The fish looks exactly like the photos. It’s very still and camouflages well. I had to adjust the lighting to avoid disturbing it. Feeding is a bit tricky, but once I got the routine, it eats regularly.

A unique and captivating species. It doesn’t move much, which is normal, but when it does, it’s impressive. I keep it with non-aggressive species and it’s never caused any issues.
