Size 194mm or 7.6" SL. Find near, nearer or same sized spp.
Identification The black top mouse catfish is very similar to another mouse catfish, Nemadoras leporhinus, the main visual difference being the latter's clear dorsal fin with a black marking at its base. Aside from that N. leporhinus has longer leading fin rays. Key characters are deep plates, pointed humeral process (vs. rounded in Leptodoras), short pointed snout, plates along back (also along ventral midline before anal fin) and tip of dorsal fin dipped in black.
Sexing Adult males have what seems to be an enlarged dorsal spine. This is however a filament (as for instance can be seen in Synodontis decora). Females lack this feature.

Feeding Until acclimatized, the fish appears quite selective and like small foods. Crushed flake or sinking flake-based tablets best for smaller individuals although brineshrimp is taken by species around the 2'' mark. Larger, more settled fish are easier to feed and become very active during feeding.
Furniture Dense vegetation empowers this fish with a much needed sense of confidence in its surroundings. Caves or dark refuges appear less important.
Compatibility Not aggressive and, as with all Doradids, sociable with its own species. Smaller fish appear to have an innate fear of larger fish and becomes very shy in their presence.
Suggested Tankmates Shoaling tetras and Brochis are ideal. Dwarf cichlids and smaller labyrinth fish (Gouramis etc) are also suitably gentile. Larger, acclimatized fish will do well in a medium to large community set-up. At any size, best kept in shoals to ensure greater boldness and health.
Breeding Unreported.
