This beautiful pencil fish has been described scientifically only a few months ago. It is quite similar to N. trifasciatus, but has a much broader central longitudinal band. The most important visual difference for aquarists is the fact that this species is sexually dichromous. Only the males have the very nice red spots in the fins.
The new species can be kept like the well known N. trifasciatus, but it is better to keep them at a bit higher temperatures (eg 24-28°C). We suggest the common name “Redmouth Pencilfish” for Nannostomus nigrotaeniatus.
For our customers: the fish have code 272184 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in limited numbers only!
