Bartlett Anthias

About this fish

Bartlett Anthias is a small, reef-aquarium saltwater fish commonly sold under the scientific name Pseudanthias bartlettorum. It’s prized for its active midwater swimming behavior and vibrant appearance, and it’s typically used as a community display fish in aquariums that can provide stable, high-quality water and frequent feeding. In many setups, anthias do best in groups and added fish are best introduced in a way that reduces territorial stress.

Features:

• Active, midwater swimmer that helps create movement through the tank’s water column
• Carnivorous diet—generally benefits from frequent feedings of appropriately sized meaty foods
• Often does best kept in a small group rather than as a single individual (species-style social behavior can occur)
• Generally peaceful toward other reef fish, but can show aggression toward conspecifics or similar-looking tankmates
• Requires stable, clean, well-oxygenated saltwater with consistent feeding and maintenance
