Size 111mm or 4.4" SL. Find near, nearer or same sized spp.
Identification Reasonably easy to ID although young fish can look quite variable. Some degree of sexual dichromatism exists and the males bear a resemblance to the larger Anadoras grypus. Very often sold under the incorrect name of Amblydoras hancockii.
Sexing Some keepers report that the underside of female is creamy white, the male is freckled as shown below. Males are more slender than the wider (when viewed from above or below) females.

Feeding A nocturnal scavenger. Younger fish tend to be a little more active during the day, but the best way to ensure this fish is properly fed is to introduce sinking food into the tank after dark. Most foods are accepted gluttonously. Individuals will gorge themselves on food to the point of appearing fit to burst.
Furniture Does not harm plants and all that is really required is a dark place in which the catfish can find refuge. Care must be taken that this is no where near the heater element as these fish will wedge themselves between the heater and the aquarium wall and may burn themselves.
Compatibility A perfect community tank resident.
Suggested Tankmates As all doradids, does well with its conspecifics and other members of the same family. Can be kept with anything from tetras to medium sized cichlids.
Breeding Has not been documented in the aquarium but reports do exist of reproduction in the wild which involves a bubble nest built in plants which the male guards. The author has collected very small ( < 10 mm SL) young Amblydoras in semi-aquatic reeds and partially submerged shrubs. No adults were collected in water about 45 cm deep. Youngsters were everywhere and one swipe of the net could turn up 10 or more young.
Breeding Reports There is no breeding report.
