Antennarius pictus is a carnivore that hunts by deception rather than pursuit. It lies still, twitches the esca to imitate a small worm or shrimp, and then engulfs whatever investigates. The mouth can expand to roughly twelve times its resting size, which allows the fish to swallow prey nearly as large as its own body. Small fish and crustaceans make up the bulk of the natural diet.
Newly imported specimens usually require live food at first, such as feeder shrimp or feeder fish, and live prey should be gut-loaded with nutritious foods before being offered so the frogfish receives full nutritional value. Many individuals can eventually be trained to take frozen meaty items waved on tweezers to mimic movement. Feed only once every four or five days, or more often in distinctly smaller portions. Overfeeding is genuinely dangerous with this species: an oversized meal can cause the fish to refuse food for weeks, and incomplete digestion of a large item can prove fatal.
Because of the swallowing risk, a species-specific display or an aquarium housing only large, docile fish that cannot be engulfed is the safest arrangement. Ornamental shrimp and crabs are poor tankmates, and even larger crustaceans are at particular risk. The frogfish does not damage hard corals, soft corals, or sessile invertebrates, so it works well within a reef aquascape, but it is reef safe only with caution given its appetite for small fish and mobile invertebrates. Avoid strongly stinging cnidarians such as elegance corals and anemones, which can injure a stationary frogfish, and avoid aggressive rock grazers that may bite at its skin.
FAQ
Frequently Asked Questions
About the Red Angler, Super
-
How often should a Super Red Angler be fed?
Offer food only every four to five days, or more frequently in noticeably smaller portions. Overfeeding can cause a weeks-long feeding strike or death from incomplete digestion of an oversized meal. -
Can this frogfish be kept in a reef aquarium?
It will not harm hard corals, soft corals, or other sessile invertebrates, so it suits reef aquascaping, but it is reef safe with caution because it swallows small fish, shrimp, and crabs whole. -
What aquascape does this species need?
Build in plenty of live rock, coral rubble, sponges, or macroalgae for perching and camouflage. Open swimming space is far less important than structure for this sedentary ambush hunter.
