Red-bar Cooperi Anthias Juv/Female, Pseudanthias cooperi, also go by the name Bleeding Heart Anthias. These fish look fantastic and even better in a large group. They are perfect for someone wanting colour and movement in their tank.

Males have a light pink coloured body, with a electric highlights down their sides. Females display more orange with a silvery belly and red tail. Males and females both sport a light blue edging around most of their fins.

Red-bar Cooperi Anthias Juv/Female, Pseudanthias cooperi, Ecology.

These fish range from: East Africa, Samoa, Japan and Australia, in the Indo- Pacific Ocean. They live on and around: coral reefs, steep slopes, channels, drop offs or caves. The complex structures help the fish dodge predators. When feeling threatened, they will quickly vanish and anchor themselves into nooks and crannies.

In nature, Red-bar Cooperi Anthias feed passively, as do most types of Anthias. Which means they stay in relatively still positions, while facing the current. When Pelagic zooplankton drifts towards them in the water, the fish snatch their food up. With this method, the hunters easily get hold of small critters and eggs, while using up the smallest amount of energy possible. Feeding is fairly constant, although other behaviours punctuate this activity.

These are fish that live in social groups, with one male to around 5 or more females. Red-bar Cooperi Anthias are also protogynous hermaphrodites. Which means when the top male dies, the largest female in the group will turn male. It will then become the new breeding male. As a result, all juvenile Red-bar Cooperi Anthias, are in fact immature females.

Bleeding Heart Anthias In the Aquarium. 

It is important to have good currents and regular feeding in order to imitate the natural environment. A wave maker can help with this. Hobbyists should think about using a jump guard to stop any unfortunate mishaps.

Red-bar Cooperi Anthias Juv/Female do best when fed a varied diet. They will accept frozen mysis shrimp and enriched frozen brine shrimp. They will also eat live foods, such as copepods and amphipods, that can be cultivated in attached refugium. Over time, these fish may have small amounts of high quality flake food as well. Our Anthias are adapted to aquarium life and most are eating a good quality frozen food, enriched with garlic guard and vitamins, before being offered for sale. We find that the best way to keep this species is in a small group. Hobbyists should aim to keep at least 1 Male Red-bar Cooperi Anthias with 3 or more females.
