10 × Dwarf Pencilfish (Nannostomus marginatus)

Each order quantity supplies 10 Dwarf Pencilfish (Nannostomus marginatus) together. The supplied size is approximately 2.5–3 cm; this is the purchase size, rather than a promise that the fish will stay that size.

Why a group?

Dwarf Pencilfish are small, peaceful social fish that settle and display more naturally when kept with their own kind. A group of ten provides far more security than a pair or trio.

Care essentials

Use a mature planted aquarium with gentle filtration, shaded areas and calm tank mates. Their small mouths need finely sized foods, and they can be outcompeted by fast or aggressive feeders.

Dark substrate, floating cover and plants around the edges help the group feel secure while leaving open areas for movement.

Before ordering

Check the current supplied size and make sure your aquarium is stable and fully cycled. Choose tank mates based on compatible water needs, adult size and feeding behaviour.
