The Blue Green Chromis is a classic schooling fish that adds constant motion and a clean, shimmering blue-green look to reef tanks. They are peaceful, hardy, and great for filling open water space, especially when kept in a small group. In the right setup, chromis bring that “reef in motion” vibe without bothering corals or most tankmates.

Why we love it

  • Shimmering blue-green colour that looks great under reef lighting

  • Peaceful, active swimmers that add life to the water column

  • Great option for small groups in larger community reefs

Suggested parameters

  • Temperature: 24–26°C (75–79°F)

  • Salinity: 1.024–1.026 SG

  • pH: 8.1–8.4

  • Alkalinity: 8–10 dKH

  • Ammonia/Nitrite: 0

  • Nitrate: Under 20 ppm (stable is best)

Care and temperament

  • Difficulty: Easy

  • Temperament: Peaceful

  • Reef safe: Yes

  • Minimum tank size: 30 gallons for one, 55+ gallons recommended for a small group

Diet

Chromis are eager eaters and do best with variety.

  • Quality marine pellets and flakes

  • Frozen mysis and enriched brine shrimp

  • Finely chopped seafood blends

  • Feed small amounts 1 to 2 times per day

Compatibility and tankmates

  • Generally compatible with most reef safe fish

  • Best kept in groups of 3 to 7+ depending on tank size

  • Provide open swimming space plus rockwork for shelter

  • In smaller groups, a hierarchy can form and weaker fish may be bullied, larger groups and adequate space can help reduce this

What you are buying

  • You will receive: 1 Blue Green Chromis (Chromis viridis)

  • Colour and size can vary slightly between individuals

As with all fish, slow acclimation is recommended, and quarantine is encouraged when possible.

LIGHT

LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.

MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height. 

HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.

FLOW

LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.

MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.

HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.

SKILL

ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.

While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
