How to Care for Anthias Fish in Your Aquarium

If you want to keep Anthias fish at home, it’s important to recreate their natural environment. They are active swimmers and need plenty of room, good water quality, and frequent feeding.

Aquarium Setup Tips

• Tank Size: Minimum 70 gallons, ideally larger for groups.
• Water Flow: Moderate to strong water movement to simulate reef currents.
• Hiding Places: Use live rock structures with caves and crevices.
• Water Parameters: Stable temperature around 24-26°C (75-79°F), salinity 1.025.

Feeding and Diet

Anthias need small, frequent meals rich in plankton-like foods such as:

• Mysis shrimp
• Brine shrimp
• Copepods
• Fish eggs

They may take several feedings a day to stay healthy because of their fast metabolism. It’s best to offer a variety of frozen or live planktonic foods and try pellets once they adapt.
