Down arrow Species Information
Size 110mm or 4.3" SL. Find near, nearer or same sized spp.
Identification Commonly referred to as A. thoracatus, a study in 2005 corrected the long standing misidentification of this species which is the most commonly available in the hobby.

When undisturbed they sport a beautiful inky bluish black colour that, in combination with many pin-prick white spots, do give the impression of a clear tropical sky at midnight hence the common name.
Sexing As with all woodcats, mature males exhibit a modified anal fin similar to the gonopodium found on many live-bearing toothcarps such as the guppy, platy, molly etc.
General Remarks Reports from the upper Essequibo River would appear to indicate a sister species.

Down arrow Husbandry Information
Feeding In the wild this fish is an insectivore, its diet probably stretches to small invertebrates and crustaceans. In captivity bloodworm appear favourite although it will readily accept flake food and sinking pellets. Food is often taken in mid-water as well as from the bottom.
Furniture Some plants can be used to provide shelter but this fish loves to cram itself into small spaces, preferably in wood, during the daylight hours. If you really want to go all out for this fish drill woodcat sized holes into a large lump of bogwood - but remember to check them for inhabitants if you ever need to remove the wood!
Compatibility Certainly a peaceful, surprisingly robust, catfish suitable for most community aquaria. Not to be trusted with very small fish as this fish is an effective hunter.
Suggested Tankmates Groups of tall-bodied smaller Characins (Hyphessobrycon etc) and Corydoras catfish perfectly compliment this catfish and their shoaling helps relax the midnight catfish in its surroundings, leading to better colouration and more frequent sightings.
Breeding Bred by German hobbyists, details (in English at least) are presently unavailable. Egg fertilization is internal and the eggs can be laid by the female in isolation from the male.
