Size 700mm or 27.6" SL. Find near, nearer or same sized spp.
IdentificationThe albino variety is more often encountered for sale than the normal colouration. Often confused with Ictalurus furcatus In juveniles the blue generally has a darker body with a whitish belly while the channel is silvery with few small dark spots. The channel cat averages 27-30 anal fin rays while the blue has 33-35. Ictalurus furcatus has a head that is wedge shaped, consistent with a blue cat's wedge shaped head is a noticeable dorsal hump in front of the dorsal fin, a channel cats head is more rounded or cigar shaped. Barbels on a blue cat are reduced in relation to I. punctatus. Also in comparison to channel cats which have a rounded anal fin the anterior margin of the anal fin is truncate in I .furcatus.
SexingIt is almost impossible to distinguish between sexes with individuals of around 10 pounds or less. Generally, the easiest way to sex a channel catfish is by the head. Mature males have a broad, muscular, kind of spade-shaped head, while the female's head is smaller and more rounded. Also, between the pelvic fins, the female has two openings. The male has just one (the anus) and a small fleshy flap (genital papillae) that sticks out a bit. The larger the fish, the easier and more distinct these differences become.
General RemarksFor aquaculture these are sometimes kept at a higher temperature for maximum growth, they can also withstand extremes in temperature, but in the home aquarium or pond the temperatures suggested on this page are for long term comfort.

FeedingAll prepared foods, youngsters can be grown very quickly on bloodworm or more cheaply on commercial fish meal. Will eat constantly, but care should be taken not to pander to this tendency as the strain on filtration becomes immense. Large individuals can be fed weekly.
FurnitureAn active catfish when young, becoming less active with age. A large swimming area is necessary to get the best from this fish. The water column need not be more than 30cm if dimly light.
CompatibilityPeaceful but predatory.
Suggested TankmatesLarge central American cichlids fit the bill both in terms of size and water conditions.
BreedingCommercially farmed in large ponds and so breeding is easily accomplished on the correct scale. This scale however does not encompass the home aquarium.
