Striped Headstander
Anostomus anostomus
Water Parameters
About
Anostomus is known for its characteristic head‑down swimming posture (headstander). Its striped body in gold, black, and red, with an upward‑facing mouth adapted for scraping algae, is unmistakable. A fascinating but demanding species in terms of compatibility.
Behavior & Temperament
Territorial fish that swims characteristically head‑down. May be aggressive toward conspecifics and similar fish. Best kept alone or in large groups (5+).
Feeding
Herbivore/Omnivore. Primarily plant-based diet: algae, cooked vegetables, spirulina-based flakes. Also accepts brine shrimp and protein foods occasionally.
Breeding
Oviparous. Reproduction is rare in captivity. Poorly documented in home aquariums.
Care Notes
Tank with plenty of hiding spots and driftwood. Use hardy plants (delicate ones will be nibbled). Provide a vegetable‑rich diet. Keep singly or in groups of five or more to diffuse aggression.
Compatibility
Compatible with similarly sized, non‑aggressive fish. Avoid other headstanders in the same aquarium unless kept in a large group. Not suitable with very small fish.
