Description:
Size
1100mm (43.3") SL
Show near, nearer or same sized spp.
Identification
An unmistakable species - the only identification woes come when examining young hybrids which appear in the hobby from time to time. The amelanistic form (absence of pigmentation but no albino pink eyes) is only found in young fish and only lasts for a few weeks. The fish revert to their normal colouration thereafter.
Sexing
Unknown, although the tail colour (which varies between red and orange / pink) and darkness of the top of the head (which varies from black to grey with black spots) vary from fish to fish. These are more likely to be due to diet and mood than sexual differences.

Husbandry Information
------------------------------------------------------------------------------Feeding
The important fact in feeding these fish isn't what it's when. Red tails should only be fed sporadically. Once fed they become sluggish and so the time to feed a red tail can be gauged by the activity of the fish. It will become permanently active when hungry. Over-feeding can be disastrous and is a common cause of death in these fish. In the wild the fish eat fallen fruit, crustaceans and fish.
Furniture
The fish does not require cover although subdued lighting should be utilised. Aquarium decor and equipment should be selected and deployed for it's own care rather than that of the red-tail. Thus the required heavy external filtration and out-of-tank heating are recommended. Red tails are renowned for swallowing items within their tanks (I.E. heater clips, filter intakes etc.); gladly these are often regurgitated but can sometimes cause serious problems for the fish. The best policy is to have as much as possible outside the aquarium.
Compatibility
This fish is territorial within confined spaces and is certainly capable of killing other tankmates. Best kept 'home alone' unless a very large aquarium is to be provided.
Suggested Tankmates
Given sufficient space (and we are talking small ponds here or public aquaria) the fish can be successfully mixed with other large Pimelodids, Doradids, Cichlids and Characins.
Breeding
Impossible within the confines of an aquarium. Commercial breeding as food fish is practiced in South America, a spin off from which are the aforementioned imports of 'kittens'. Aquaculture has also given us hybrids of Red tails and Tiger Shovelnose (Pseudoplatystoma sp.) Also shown above is the inappropriately named white red tail which is very uncommon indeed.
