The Freshwater Lionfish (Batrachomoeus trispinosus) is a most interesting fish that can be kept in the brackish water aquarium. These unusual fish are found in the muddy bottoms of mangrove estuaries and coastal waters.
The Freshwater Lionfish is truly an oddball fish, and rather grumpy. The names of Toadfish, Frogfish and even Stonefish give a good impression of what this fish looks and acts like. It sits very still and looks much like a camouflaged brown lump or stone, thus the name Stonefish. The broad head and large mouth are very frog-like. It also feeds very much like a frog or toad would, waiting patiently until its food comes within range and then gulping it down quickly.
The Freshwater Lionfish gets to be quite large, reaching almost 12 inches (30 cm) in length. But despite its large size, it really doesn't need a large tank because it is quite still most of the time. It is camouflaged to blend in with its surroundings. It is peaceful, but it is a predator. Choose tank mates that are too large to fit into its cavernous mouth.
The Freshwater Lionfish are carnivores, a predator. In the wild they feed on live crustaceans and fish. In the aquarium feed a variety of foods including bloodworms, earthworms, river shrimp and crayfish. Some fish foods that you can offer include tilapia, rainbow trout, pollack, and cockles. Prawns and shrimp can be used in the short term to get your fish eating.
This fish relies on camouflage and stealth to get a meal so if their prey doesn't swim directly in front of them, they may not get enough to eat. Using a feeding stick, aquarium tongs, or forceps to hold foods in front of their mouth is a good way to make sure that it is getting enough to eat. It may take awhile to get one to feed so be patient. Be careful not to overfeed these rather sedentary fish. Provide just enough so that the belly fills out slightly but doesn't look inflated.
