Altum Angelfish (Pterophyllum altum)

Quarantined freshwater angelfish for taller planted aquariums and carefully selected community setups.

The true Altum Angelfish is a highly prized South American angelfish species from the Orinoco and Casiquiare region, admired for its exceptionally tall body, elegant barring and commanding presence. It is a premium species best suited to experienced aquarists planning a spacious, mature display aquarium.

Why This Angelfish Stands Out

• True Pterophyllum altum rather than a domestic altum-type scalare strain
• Exceptional vertical height and refined natural patterning
• Locality-labelled options from the Orinoco / Casiquiare region

Aquarium Setup & Behaviour

Altum Angelfish require a very tall, spacious, mature aquarium with excellent stability, oxygenation and careful tankmate selection. Height is especially important because adults develop a much taller profile than typical domestic angelfish.

These are social cichlids that may be maintained in appropriately planned groups, while mature pairs can become territorial. Their sensitivity and adult size make them a specialist choice.

Feeding

Offer an excellent varied diet with high-quality prepared foods and appropriate frozen/live supplementation; avoid unstable husbandry or sudden changes.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Although angelfish may be described in literature as preferring softer or more acidic natural conditions, we prioritize stable systems, gradual acclimation, good filtration, and healthy feeding before they become available to customers.

Frequently Asked Questions

Is true Altum Angelfish the same as a domestic angelfish labelled altum-type?
No. True Altum Angelfish are Pterophyllum altum, a distinct species; domestic altum-type angelfish are generally selected Pterophyllum scalare forms.

Why does locality matter for Altum Angelfish?
Locality labels such as Rio Orinoco or Casiquiare help identify the geographic origin or trade line of these highly valued fish.

Are Topick Altum Angelfish kept in local tap water?
Our Altum Angelfish are quarantined and conditioned to our stable local tap water before sale. Because this remains an advanced and more sensitive species, a mature aquarium and careful acclimation are still essential.
