Blue Devil Damselfish

About this fish

Blue Devil Damselfish is a saltwater damselfish for the home aquarium, sold under the scientific name Chrysiptera cyanea. This active, colorful reef fish is often chosen for new tanks because damselfish are generally hardy and adjust well to established reef setups. It also serves as a lively addition to community displays, with practical tank-planning around their social behavior so you can enjoy their personality without constant conflict.

Features:

• Active, fast-moving swimming behavior that adds life to the aquarium
• Generally hardy and well-suited to many home saltwater setups
• Often considered reef safe with corals
• Can become territorial as it matures, especially toward similar-looking tankmates
• Provides best results in tanks with plenty of rock for territory building
• Can be kept with planned, compatible tankmates; chromis-type groups are typically more peaceful (species-dependent)
• Feed small frozen foods plus quality flakes or pellets once or twice daily
• Acclimate slowly and offer a quieter spot in the tank to help it settle
