Redtail Catfish - in The Aquarium

In The Aquarium

The redtail catfish is an extremely popular fish in Amazonian themed exhibits at public aquaria, where they are often housed with other large fish such as Colossoma macropomum, Arapaima gigas, and other large catfish.

Juveniles are often available as aquarium fish despite their eventual large size. In an aquarium where they may be well-fed, these fish can grow quite rapidly. Weekly feeding is appropriate for this catfish; overfeeding is a common cause of death in this species. It feeds heavily on live and dead fishes and other meat. Even as a juvenile of only a few inches in length, they are able to swallow many of the more common aquarium fish such as tetras, and it is only appropriate to house this fish with other species of relatively large size. Redtail catfish also have a habit of swallowing inedible objects in the aquarium. Though these are often regurgitated, both the swallowing and the regurgitation can present a problem for the fish, and these objects are best kept out of the aquarium. It is important that these fish are housed in large aquariums. A minimum size tank for a full grown (4-5 feet) is 1000+ gallons.

Famous quotes containing the word aquarium:

    one is in a shoe factory cursing the machine,
    one is at the aquarium tending a seal,
    one is dull at the wheel of her Ford,
    one is at the toll gate collecting,
    one is tying the cord of a calf in Arizona,
    one is straddling a cello in Russia....
    Anne Sexton (1928–1974)
