Aquarium care

Feeding

Beckford's Pencilfish enjoys a varied diet rich in proteins, including high-quality flake food, pellets, and live/frozen foods. Though they are not picky eaters, food portions should be appropriate to their small mouths, with granules being crushed if necessary.

Compatibility

Golden pencilfish are peaceful and compatible with a variety of community fish. They do best in a well-planted tank and should not be kept with overly aggressive species.

Breeding
