Water parameters
Overview
Leopold's angelfish is the smallest and least known species of the genus Pterophyllum. The dark vertical bands on its silver body resemble those of the common angelfish, but its forehead profile is straight and there is a distinct dark spot at the base of the dorsal fin. Its fins are shorter, so its body looks stockier. It is rare in the trade and is sold as wild-caught or as a small number of captive-bred fish.
Tank Setup
- At least 200 liters for a group of 4–6; water height of 45–50 cm or more.
- Soft, slightly acidic water at 27–29°C; a tannin-rich setting with leaves and roots.
- Vertical roots, tall plants and dim light; a quiet corner.
- A 25–30% water change weekly; avoid sudden changes in values.
Diet
Omnivorous. Alongside small granules and flakes, offer frozen brine shrimp, bloodworms and mosquito larvae. Newly arrived fish may at first accept only frozen food.
Behavior and Compatibility
Calm and shy; it becomes bolder in a group. Like the common angelfish, it may eat small fish that fit in its mouth.
Good companions: medium-sized tetras (rummy-nose tetra, Congo tetra), corydoras, otocinclus, Biotodoma, discus.
Avoid: very small fish such as neons and cardinals, fin-nipping barbs, aggressive cichlids, shrimp.
