The Red Bar Anthias (Pseudanthias cooperi), also called Cooper’s Anthias, is a mid-water anthias with a light pink body and a distinct red bar, with blue edging along the fins. In mixed reef displays, it adds constant open-water movement while still using rockwork ledges as “home base.”
What You’ll Observe:
- Spending most of the day hovering in the middle of the tank and rising into the water column at feeding time
- Quick, coordinated dashes back to caves and ledges, then returning to the same mid-water zone
- A clear social pecking order when kept as a small group, with regular short display swims
- Color becoming richer during active periods, especially around feeding and interactions
To do well with this species, provide an aquascape with multiple caves/overhangs plus open swimming lanes in front of the rockwork. Offer small, meaty plankton-sized foods in multiple small feedings to match its natural feeding style, and maintain a consistent routine so it stays active in the water column.
Is it normal for a Red Bar Anthias to disappear into the rockwork at first?
Many settle in by choosing a specific cave/ledge and then expanding their “patrol area” over the next several days as they learn the tank’s rhythm.
Do Red Bar Anthias do better with pellets, frozen, or a mix?
Most keepers report the smoothest results with a mix, using smaller particle sizes so the fish can take bites quickly in the water column.
How do you keep up with frequent feedings without being home all day?
A common approach is to split the daily amount into smaller portions and automate at least one feeding, then use frozen for the remaining feeds when you’re home.
Can a group change sex, and how long does that transition take?
In groups, the dominant fish can transition over a period of weeks, often showing “in-between” coloration while the hierarchy stabilizes.
Can you keep more than one male in the same tank?
Some hobbyists report success in larger groups where attention is spread out, but most aim for a single clear dominant male to keep the group dynamic steady.
Each fish is checked for strong appetite and activity before we approve it for your tank.
