Sargassum Angler - Histrio histrio - Small
Sargassum Anglers (Histrio histrio) are usually striped brown and yellow and have skin flaps on their bodies to blend with the Sargassum macroalgae with which they are usually found floating. Patterns will vary between individual fish so no two will look exactly alike. The lures on these frogfish are very short and the pelvic fins and overall body shape are longer than other species. This is the only frogfish with a swim bladder and tends to be more buoyant and active than other species. The aquarium should be kept covered as these fish have been known to jump from the water if threatened.
The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species.
These fish are often difficult to identify down to an exact species because of their very high variation in colors and patterns. They can also often change color and pattern to better blend in with their surroundings. With a few distinctive exceptions, most are extremely variable and may be different than the example pictured here. Many anglers and frogfish are identified by the shape of their esca (the "lure") and their illicium (the "fishing rod" part that holds up the lure).
Anglers and Frogfish are ambush predators and can eat almost anything small enough to fit into their (very large) mouths. This can include other fish as well as inverts like crabs, shrimp and others. Use caution when choosing tankmates. These fish are not very active and can be kept in a fairly small tank (depending on species) and can be kept alone as a "species-only" showcase.
They will typically eat almost any meaty foods offered but may only accept live items at first. Though they should be weaned onto frozen at some point, live ghost shrimp, mollies, guppies and similar items can be used at first. Eventually, they can be trained to accept frozen clam, squid, shrimp, krill and similar items. It is not unusual for these fish to fast the first few days to even weeks once introduced to a new environment or after a particularly large feeding.
