Down Species Information
Size 45mm or 1.8" SL. Find near, nearer or same sized spp.
Sexing Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
General Remarks Only ten specimens were collected by scientists and are stored in museum collections and it's a very infrequent aquarium import. The description of the fish doesn't help with identification as (a) there are now several other similar species described and (b) the type material was sub-adult or juvenile fish.

Down Husbandry Information
Feeding This species will readily accept all prepared foods that reach the bottom of the aquarium such as tablets, granules and larger flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm (Enchytraeus), Daphnia and Tubifex are readily accepted and good for conditioning groups of fishes for spawning. User data.
Furniture Ideally substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig. Substrate should be bordered with driftwood and aquatic plants leaving an open area for them to search for food and swim. The shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required to settle these fishes.
Compatibility A peaceful, shoaling, community fish.
Breeding Unreported.
Breeding Reports There is no breeding report.
