Feeding Guide

Feed a varied diet of high-quality tropical foods, including fine granules, crushed flakes, frozen bloodworm, brine shrimp, and other suitable protein-rich foods. Small juveniles benefit from little-and-often feeding with close attention to water quality.

Tank Setup & Habitat

Altum-type angelfish appreciate a tall, mature aquarium with gentle water movement, stable warm temperatures, and excellent filtration. Use wood, plants, and shaded areas to create a calm environment with open swimming space. As they grow, tank height becomes especially important to support their natural body shape and fin development.

Compatibility

These angelfish are best kept with peaceful tank mates that are not small enough to be viewed as food and not aggressive enough to nip fins. Suitable companions may include larger peaceful tetras, peaceful corydoras, and other calm South American species in a properly sized aquarium.

Health & Wellness

Because these are small juvenile fish, stable water quality and careful acclimation are essential. Avoid sudden changes in temperature or chemistry. Clean, warm water and a low-stress environment are key to strong growth and long-term health.

Acclimation Guide

Float the bag to equalise temperature, then gradually add aquarium water over 20–30 minutes before release. Keep lighting subdued and avoid feeding immediately while the fish settle into their new environment.
