Passer Angel

About this fish

Passer Angel is sold as a marine angelfish, listed under the scientific name Halocanthus passer. In an aquarium, this fish is typically kept for its distinctive angelfish profile and active swimming behavior, and it is commonly used as a showpiece in a well-established saltwater tank with plenty of live rock for grazing and shelter.

Features:

• A marine angelfish (Halocanthus passer) intended for saltwater aquarium setups rather than freshwater systems.
• Best suited to a mature, stable tank because angelfish generally do better when water quality is consistent and hiding space is available.
• Uses the live-rock habitat to explore and feed, so providing rockwork and visual cover can help it settle in.
• Diet is usually omnivorous; most angelfish do well with a varied routine of prepared foods and occasional meaty items.
• May show angelfish-typical behavior such as nipping at certain sessile invertebrates; housing with reef life should be planned with care.
• Often benefits from tankmates that can tolerate a degree of angelfish assertiveness, especially in smaller aquariums.
