Comprehensive Guide – Sargassum Angler – (Histrio histrio)

The Sargassum Angler, also known as the Sargassum Frogfish or Sargassum Fish, is a unique and fascinating species to keep in a saltwater aquarium. Let’s explore some key aspects of this fish:

Habitat

The Sargassum Angler is found in tropical and subtropical waters of the Atlantic Ocean, particularly in the Sargasso Sea. It inhabits floating seaweed, where it camouflages itself among the fronds.

Reef Safe

The Sargassum Angler is not considered reef safe. It has a tendency to eat small fish and invertebrates, which makes it unsuitable for a reef aquarium with delicate corals and other invertebrates.

Size

The maximum size of a Sargassum Angler is about 6 inches. It starts small but grows relatively quickly in the right conditions.

Temperament

The Sargassum Angler is an aggressive fish, especially towards smaller tankmates. It is best kept alone or with larger, similarly aggressive fish in a species-specific tank.

Sexual Dimorphism

There is no significant difference in appearance between males and females of this species, making it difficult to determine their gender visually.

Lifespan

The average lifespan of a Sargassum Angler is around 5 to 7 years when provided with proper care and optimal tank conditions.

Diet in Aquariums

The Sargassum Angler is a carnivorous species that primarily feeds on small fish and invertebrates in the wild. In an aquarium, it can be trained to accept frozen or live meaty foods such as shrimp, krill, and small fish.

Aquascaping Recommendations

Creating an environment that mimics the Sargassum Angler’s natural habitat is important. Providing ample hiding spots with live rock or artificial structures resembling seaweed will help replicate its preferred surroundings.

Captive Bred Availability

Currently, the Sargassum Angler is not commonly available as a captive-bred species. Most specimens in the aquarium trade are wild-caught.

Compatibility with Other Fish, Invertebrates, or Corals

Due to its aggressive nature, the Sargassum Angler is best kept in a species-specific tank. It may not tolerate other fish or invertebrates, especially smaller or more passive species. However, if you wish to add tankmates, choose larger, robust fish that can hold their own against the angler’s aggression. Five potential tankmates include:

1. Blue Tang – Known for its ability to withstand aggression and its striking coloration.
2. Snowflake Moray Eel – A hardy eel species that can tolerate the angler’s aggressive behaviors.
3. Yellowtail Damsel – A feisty damselfish that can hold its ground against the angler.
4. Clown Triggerfish – A larger and more aggressive fish that can coexist with the angler.
5. Red Hermit Crab – A sturdy and opportunistic scavenger that won’t be bothered by the angler’s presence.

Other Common Names

The Sargassum Angler may also be known by other common names, such as Sargassum Frogfish, Sargassum Fish, or Sargassum Seaweedfish.
