A male F. acus has a broader snout with short bristles. Sometimes difficult to tell and breeding in captivity very rare.

Tank compatibility[edit]

As many suckermouth Catfish do, Farlowellas spend much time sticking to the glass, plants, or other decorations. They should not be kept with overly aggressive fish for they are relatively fragile despite their armour.


Mostly vegetable matter such as cucumbers, zucchini, squash, or blanched lettuce, supplemented with small crustaceans like ghost shrimp or brine shrimp. They should adapt well to dry foods such as sinking algae wafers.

Feeding regime[edit]

Feed once or twice a day, will be most active in dimly lit tanks or when the tank light is off.

Environment specifics[edit]

Provide this fish with a well filtered and mature tank. They prefer a sand substrate with rounded river rocks and smaller pebbles. Driftwood or bogwood is mostly absent from their natural habitat but the congregate where bamboo stalks hang into the water. It is only found in cool rivers and streams with a fair amount of current.


A peaceful fish that is fairly inactive and unwilling to compete with other fish for food.


Has a shorter snout then Farlowella gracillis. It is a very slender fish with a pointed snout that does well to resemble a long twig! It is mottled brown in colour.
This fish is now endangered in the wild and is rarely imported. Other species may be sold under their latin name however.
