Habitat Inhabits large rivers and lakes. This can lead to health problems in the long term. It also has an amazing set of very long barbels that can move independently of each other.

This species should not be fed the meat of mammals such as beef heart or chicken.

Leiarius marmoratus

Risks involved with feeding these include the potential of disease introduction. Apparently they also differ slightly in the morphology of the skull.

Also take care not to overfeed. Very few fellow hobbyists will have the facilities to do so, either. Larger specimens can be offered whole fish fillets use white fish.

Try to keep the diet varied or you may find it becomes too accustomed to a particular food and is reluctant to accept anything else.

All too often, juveniles are sold without adequate information marmkratus their long term care. Particularly suitable companions include Doradids such as Oxydoras nigerMegalodoras urunoscopus or Pterodoras granulosus.


Marbled Pim

Virtually impossible to sex by external characteristics. An adult specimen needs only a single meal per mwrmoratus at most. Adult females are likely to be stockier in build than males.

These cats can and will attain something close to their maximum size in captivity, and will do so quite quickly. Some of the lipids contained in these meats cannot be properly metabolised by the fish, and can cause excess deposits of fat and even organ degeneration.

Some hobbyists simply leave the substrate out altogether, which certainly makes cleaning the tank an easier task. This is now considered a junior synonym of L. If possible, choose a sump — type arrangement, as this allows most of the equipment to be located outside the tank.

A large and leiarus biological filter is marmiratus to cope with the amounts of waste produced by a fish of this size. You can however add some large chunks of bogwoodbeech branches or smooth rocks if you wish. Choice of substrate can be an issue, as most grades of gravel can either be swallowed or become caught in the delicate gills. Further confusion arises when attempting to distinguish it from the very similar, but much rarer Perrunichthys perruno.

Many aquarists buy a young specimen with the intention of buyinga bigger tank as it grows. If the tank is also very deep larger characins, cyprinids, South american arowana and various cichlids such as Cichla species can also be added.


Feed every other day when juvenile but as the fish grows reduce the frequency. A layer of large, smooth pebbles is a better option.

Inhabits large rivers and lakes. A large specimen can easily destroy glass heaterstats, thermometers etc. You must be logged in to post a comment. Piscivorous by nature, but usually adapts well to dead foods in leiafius.

The only visible difference appears to be in the number of dorsal fin rays. Sexual Dimorphism Virtually impossible to sex by external characteristics.

Reproduction Unreported in captivity. Juveniles enjoy hiding places in the form of bogwoodtangles of roots and branches, rock piles or lengths of plastic piping of a suitable bore. It lurks among submerged tree roots and other refuges during daylight hours, emerging at night to feed. It relishes meaty msrmoratus such as prawns, mussels, cockle, lancefish or earthworms.
