Size 110mm or 4.3" SL. Find near, nearer or same sized spp.
IdentificationCommonly 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.
SexingAs 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.

FeedingIn 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.
FurnitureSome 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!
CompatibilityCertainly 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 TankmatesGroups 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.
BreedingBred 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.

These have laid eggs on a few occasions, but due to the setup and timing of these events I was unable to attempt raising the fry. There were no other species present during the last spawning, so the eggs had to be from these. Added another specimen Oct 2010. Looks to be female.", (5) roy.bryan, (6) Kjlossman, (7) k1ttyme0w, (8) Hammerhead, (9) ali12345 (k: 5), (10) Angelface23 (k: 14), who also notes: "I'm fairly certain I only have one male out of my group, but I wasn't really interested INTERESTED in them until recently. Recently added were 6 more, and they appear to be all female. Numbers may change once I get them to calm and can study them.
