The Blue Green Chromis (Chromis sp.) is a reef-safe schooling damselfish with an iridescent blue-green body that reads more blue or more green depending on your lighting. In reef aquariums it’s commonly used as an open-water “shoaling” fish that keeps the upper water column active.
What You’ll Observe:
- A loose group that cruises the top and midwater, often tightening up briefly during feeding
- Quick, coordinated dashes back toward rockwork when startled, then right back out to swim
- Short “ranking” displays inside the group, with most of the day spent calmly hovering and swimming
- Confident feeding in the water column, especially when offered small foods that stay suspended
For best results, provide open swimming room plus branching rock structure for the group to tuck into at dusk. Offer a mix of fine pellets and small frozen foods (like mysis or copepod-sized blends) 1–2 times daily so they can feed naturally in the water column.
Do Blue Green Chromis stay in a tight “school” all day?
Most of the time they form a loose shoal, and they’ll bunch up more tightly during feeding or when something moves quickly near the tank.
Is it better to add a group all at once or one at a time?
Adding them together tends to create a more natural group dynamic from the start, so they settle into a steady routine faster.
Why does one Chromis sometimes look a little more yellow or “different” than the rest?
Color shifts are common with mood, lighting, and social behavior; during breeding behavior, individuals can show stronger yellow-green tones.
Where do they go at night?
Many will choose favorite “parking spots” in the rockwork and return to the same general area at lights-out.
How do I feed them without them grabbing everything immediately?
Broadcast feed across a wider area (or use alternating flow) and offer two smaller portions so food stays in the water column long enough for the whole group to eat.
Each fish is checked for strong appetite and activity before we approve it for your tank.
