Overview
The Roman nose angelfish is the smallest of the wild angelfish, a mostly peaceful cichlid for a community tank. It suits a keeper with some experience.
Did you know
The Roman nose angelfish has a smooth, straight forehead with no notch or dip above the eye, unlike the common angelfish. That nose line is the source of its name.
Caring for the Roman nose angelfish
Give a small group of Roman nose angelfish at least 30 gal (115 L), since they appreciate height. Tall plants, vertical driftwood and some floating cover suit their deep bodies and break up sight lines. Add leaf litter and keep the filtration gentle, which helps them relax enough to show their silver and black barring.
Keep the water soft to neutral, at 72 to 84°F (22 to 29°C) and a pH of 6.0 to 7.2. Feed a varied diet of flake or micro pellets with frozen and live foods, such as bloodworms and brine shrimp.
Keep Roman nose angelfish in a school of six or more. A group spreads out the squabbling between individuals, especially as pairs form, and lets the fish settle into a natural order.
It is regarded as the feistiest of the wild angelfish, but it is generally peaceful in a community. It leaves most tank mates alone, though very small fish and shrimp may be eaten. Pair it with mid-sized tetras, rasboras and peaceful catfish.
Like other angelfish, it is an open spawner. It lays rows of eggs on a cleaned vertical surface, such as a leaf or a piece of wood. Both parents guard the eggs and fry.
Good to know
Pterophyllum leopoldi is a member of the cichlid family, Cichlidae, and one of three wild angelfish species. A dark blotch where the dorsal fin meets the body also tells it apart from the common angelfish. It also goes by the name long nose angelfish.
In the wild
The Roman nose angelfish comes from the Amazon in Brazil and from the Guyana region. It lives among submerged wood, roots and plants in slow, warm, softly acidic water. Its home waters are shaded, tannin-tinted backwaters.
