Bicolor Angelfish

About this fish

Bicolor Angelfish (Centropyge bicolor) is a marine angelfish for the home saltwater aquarium, popular for its striking patterning that often becomes more pronounced as it grows. In practical terms, it’s a visually engaging centerpiece fish that can also help keep live rock surfaces and algae grazed down. Because many angelfish may also pick at desirable reef organisms, it’s best used with careful tank planning—especially in aquariums that contain corals or clams.

Features:

• Dwarf-angelfish profile makes it well-suited to many home reef and fish-only setups, depending on tank size and stocking
• Bold, contrasting patterning can change as the fish matures
• Typically benefits from a varied diet including quality frozen foods and algae-based options
• May nip or graze on some corals or clam mantles, so reef compatibility should be considered before adding
• Best kept with thoughtful stocking; limiting to one angelfish per tank is often recommended unless your system is very large
• Arrives best after slow acclimation and a quiet settling period

Specifications:

• Care level: Intermediate (needs stable marine conditions and appropriate feeding)
• Temperament: Generally aggressive toward similar tankmates; best kept as the only angelfish unless the aquarium is large
• Adult size: Dwarf angelfish size (varies by individual and conditions; plan for a small-to-medium aquarium fish)
• Diet: Varied diet of quality frozen foods, sponge-based formulas, and algae
• Feeding frequency: Several times a day
• Water temperature: Typically in the mid-70s °F (commonly 72–78°F for marine fish)
• pH: Typically around 8.1–8.4
• Salinity: Typically 1.020–1.026 specific gravity
