Nannostomus marginatus

Alternative names

 * Dwarf Pencilfish

Sexing

 * Adult males are slimmer and may show more red in their fins than the females. These fish are difficult to breed in captivity.

Tank compatibility

 * Would do well in a pygmy community tank, but do not keep with fish that could swallow this little fish! Would do well with small Tetras, Rasboras and dwarf Corydoras. Not strictly a shoaling fish, but keep in groups of 3-4 or more.

Diet

 * Omnivores, will take most small foods including crushed flakes or pellets, and small live foods such as daphnia and brine shrimp.

Feeding regime

 * Feed once or twice a day.

Environment Specifics

 * Prefers a well planted mature tank with good filtration, but not a strong current. They do not appreciate very bright lighting so floating plants are desirable.

Behaviour

 * Doesn't need to be shoals, but prefers company of 3 or more. A peaceful mid-swimming fish.

Identification

 * This fish has two bold horizontal black lines with two white lines accompanying. Red and some yellow on the fins with hints through the body.
