Golden Pencil Fish

The Golden Pencilfish is a peaceful species which should be kept in groups of 6 or more fish. The aquarium should have a dark substrate and background with plenty of plant cover, both rooted and floating. Occasionally males may bicker with one other, but no harm should ensue, particularly if there is a good network of plants for them to retreat to if necessary. Keeping more females than males also helps reduce aggression-related problems. Can be safely kept with other small fish of a similar disposition. Colours can vary, depending on the geographical location that they originated from. Acclimatisation should be carried out very carefully, and once settled into a good environment, the colours of these fish will really intensify.
