The offspring of Manonichthys alleni are possible. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. If you are interested in Manonichthys alleni, please ask your dealer for offspring. If you already own Manonichthys alleni, try breeding yourself. This will help to improve the availability of offspring in the trade and to conserve natural stocks.
J. Frische ("DAS AQUARUM, November 2004") wirtes: Males are daker than femals and smaller as well.
Should be kept like other Pseudochromis. By far not as agressiv as P. aldabraensis.
Manonichthys alleni inhabits caves and under ledges of coastal fringing reefs.
The Sabah dottyback has been observed to inhabit the tubular sponge Callyspongia (Cladochalina) aerizusa Desqueyroux-Faúndez, 1984.
