Large Abramite Headstander (3.75-4”)

Scientific Name:

Abramites hypselonotus

Maximum Size:

Up to 6 inches (15 cm) in length.

Recommended Aquarium Size and Care:

• Minimum Tank Size: 40 gallons (150 liters) for a single adult; larger tanks (55+ gallons) recommended for groups or kept with other fish.

• Tank Setup:

  • Substrate: Sand or fine gravel.

  • Decor: Driftwood, rounded rocks, and hardy plants (be aware they may nibble on vegetation).

  • Filtration: Strong filtration is necessary to maintain clean, oxygenated water.

  • Water Parameters:

    • Temperature: 72–80°F 

    • pH: 6.0–7.5

  • Current: Appreciates moderate to strong water movement, mimicking river flow. A wavemaker is create to have in the aquarium to create strong flow for them.

• Tank Mates: Best kept with similarly sized, peaceful to semi-aggressive fish. Avoid small, delicate species due to occasional fin-nipping or boisterous behavior.

• Silver Dollars, Tinfoil Barbs, Scats, Electric Blue Acara, Polar Parrots

Diet:

• Feeding Type: Omnivore with a strong preference for vegetation.

• Foods:

  • Blanched vegetables (spinach, zucchini, cucumber)

  • Algae wafers

  • Spirulina flakes

  • Sinking pellets

  • Occasional protein treats: bloodworms, brine shrim

• A well-balanced, mostly plant-based diet 

Overview:

The Abramite  is a uniquely shaped freshwater fish known for its head-down swimming posture, which allows it to graze on algae and detritus from submerged surfaces. It belongs to the Anostomidae family, commonly referred to as "headstanders."

These fish are active, quirky swimmers that add interesting behavior to South American or riverine-themed aquariums. Due to their potential for territoriality and boisterous nature, careful planning of tank mates and ample space is essential.

Natural Habitat:

• Geographic Range: Native to South America, particularly in Colombia, Venezuela, and parts of the Amazon Basin.

• Habitat Type: Fast-moving rivers and streams with rocky or sandy substrates, submerged roots, and marginal vegetation.

Breeding:

• In Captivity: Breeding is rare and challenging in home aquariums.

• Reproduction Type: Egg-scatterers.

• Spawning Conditions: Little is known about exact triggers, though like many South American species, seasonal changes in water parameters may be necessary (soft, acidic water, increased flow, temperature fluctuations).

• Parental Care: No parental care; eggs are scattered and may be eaten if not removed or separated.
