With a body of mottled brown and tan, the Sargassum Frogfish projects an ornate rock-like appearance that that of fish. Unlike other frogfish, the skin of this fish is smoother rather than prickly. The Sargassum Frogfish is a master of camouflage in its habitat and can change from light to dark in coloration. It completely mimics the Sagassum algae with folds and tufts of skin. The Sargassum frogfish?s skin is covered with dermal flaps, which enable it to blend in even better. Adults are sometimes seen swimming under clumps of floating Sargassum weed. When threatened by a predator the Sargassum Frogfish sometimes jumps out of the water onto the top of an algal mat. It may stay out of water for some time. The Sargassum Frogfish grows up to length of 6 inches and should be kept in a tank not less than 30 gallon along with plenty of places to hide and swim. It thrives well in a moderate temperature and pH of 8.1-8.4. The Sargassum Frogfish may be aggressive towards other filefish and should be kept as a single specimen or as a male-female pair. The Sargassum Frogfish 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 Fish has been known to devour fish nearly equal to its own size.
What a fascinating fish! These fish swallow up their prey in lightning fashion. When keeping with other tankmates remember that their eyes are way bigger than their stomachs. It is amazing to watch them eye their prey and move at speeds almost quicker than the human eye can recognize as they swallow them up whole. Another amazing feature about this fish is that its circular gills actually reside below the pectoral fins. Through the wonder of creation this gill location is designed to prevent the prey from noticing any movement around the head of the Angler, keeping it totally still and camouflaged as it hunts.
