Overview
The talking catfish is a hardy, peaceful bottom dweller, and an easy oddball to add to a community tank.
Did you know
Lift a talking catfish out of the water and it will often grunt and creak at you. The sound carries surprisingly well through the air.
Caring for the talking catfish
Give the talking catfish a tank of at least 26 gal (100 L) with a soft sand bottom. Add plenty of driftwood, leaf litter and dark caves for cover, since it spends much of the day out of sight.
Keep the water soft to neutral, at 72 to 82°F (22 to 28°C) and a pH of 6.0 to 7.5. Feed sinking pellets, frozen bloodworms and other meaty foods after the lights go out.
Talking catfish are peaceful, and one is fine alone or in a group. It will not bother tank mates it cannot swallow, but it may eat very small fish and shrimp at night. Take care when netting it, because its locking spines tangle badly and it can jab you. There is no record of it breeding in home tanks.
Good to know
Acanthodoras spinosissimus is a thorny catfish of the family Doradidae, armored with a row of bony, spined plates along each flank. Like other doradids, it makes audible grunts and creaks by grinding its pectoral spines and vibrating its swim bladder. It usually makes these sounds when it is handled or stressed.
In the wild
The talking catfish lives in slow, leaf-littered stretches of the Amazon and Essequibo river basins in northern South America. It roots through soft substrate and detritus for food. It is nocturnal and often buries itself during the day, leaving just its eyes showing.
