Black Bar Chromis

About this fish

Black Bar Chromis is a saltwater damselfish/“chromis” for the home aquarium, sold under the name Chromis retrofasciata. Chromis are popular because they’re typically hardy, active swimmers that add movement and color to reef or fish-only setups. In practice, they’re a great choice when you want a more peaceful damselfish that can do well with compatible tankmates—especially when kept in a small group.

Features:

• Hardy and active, helping bring lively movement to the tank
• Generally reef-safe with corals, making it useful for mixed reef aquariums
• Chromis are usually more peaceful than many other damsels, especially when kept in groups
• As damsels mature, some can become territorial—plan tankmates with care
• Provide plenty of rock so the fish can establish comfortable space in the aquarium
• Feed small frozen foods along with quality flakes or pellets once or twice daily
• Acclimate slowly and allow a quiet settling-in period when the fish arrives
