Midnight Angelfish Care Guide

Tank Requirements

Provide at least 55 gallons with mature live rock for grazing. The Midnight Angelfish thrives in stable reef environments with plenty of hiding spots. Maintain salinity at 1.023–1.025, temperature between 72–78°F, and strong filtration.

Diet & Feeding

Feed a varied omnivorous diet including marine algae, spirulina, mysis shrimp, brine shrimp, and high-quality angelfish preparations. Offer multiple small feedings daily for optimal health and coloration.

This species is considered reef safe with caution. While many individuals ignore corals, some may nip at LPS, zoanthids, or clam mantles. Best introduced after more peaceful fish and monitored during initial weeks.

Behavior & Tankmates

Semi-aggressive toward other dwarf angelfish. Avoid housing with similar Centropyge species unless tank size exceeds 100 gallons. Compatible with tangs, wrasses, gobies, and clownfish.
