Blueberry Canary OB Hap Care Guide - Setup, Diet & Breeding

Blueberry Canary OB Hap is a striking ornamental form of the Lake Malawi hap Sciaenochromis fryeri. Mature males typically develop an intense blue ground colour, often contrasted by orange or copper irregular blotches associated with the OB, or orange-blotch, pattern. The exact balance of blue, yellow and orange varies considerably between individual fish and breeding lines.

Like other haps, this fish has a streamlined, moderately deep body and a large mouth suited to taking animal prey. Males are generally more vividly coloured than females, although females and young fish can still show attractive silver, grey or warm orange-brown markings.

In aquaria, Blueberry Canary OB Haps are active, confident cichlids that occupy open water around rocky territories. Males can be strongly territorial, especially when displaying or spawning, and their temperament varies with the individual, tank layout and available space.

The wild Sciaenochromis fryeri is associated with the clear, alkaline waters of Lake Malawi, where it hunts smaller fish and other prey around rocky habitats and open areas. The Blueberry Canary OB form is produced through selective breeding in captivity, so its appearance and exact lineage may differ between suppliers.

The Blueberry Canary OB Hap is a selectively bred aquarium form associated with Sciaenochromis fryeri, a haplochromine cichlid native to Lake Malawi in East Africa. The trade name describes a cultivated colour and pattern rather than a naturally occurring wild population.

A group should have at least a 300-litre aquarium, with a larger tank preferable for multiple males or a mixed Malawi community. Aim for a footprint of roughly 120 x 45 cm or greater, rather than relying only on height. Use a fine sand or rounded-gravel substrate, sturdy rockwork that creates caves and visual barriers, and generous open swimming space. Secure rocks directly on the tank base before adding substrate, because these cichlids may dig and rearrange the aquarium. Strong filtration, good oxygenation and stable, alkaline water are important, while hardy plants such as Anubias can be used if desired.

Males can reach about 20 cm (8 in) in aquarium conditions, while females are usually smaller at around 14–16 cm (5.5–6.3 in). Because this is a selectively bred trade form, adult size can vary with lineage, sex and husbandry.

Offer a varied, protein-rich cichlid diet based on quality carnivorous or omnivorous African cichlid pellets and granules. Frozen or live foods such as mysis shrimp, brine shrimp, daphnia and finely chopped seafood can be used as occasional supplements. Feed modest portions once or twice daily and remove uneaten food. Avoid relying on fatty mammalian meats, and do not make large amounts of fibrous spirulina-based food the main diet, as this species is primarily adapted to animal prey.

Suitable companions include similarly sized, robust Lake Malawi haps and peacocks with comparable water requirements and a reasonably calm temperament. Examples may include Placidochromis, Copadichromis, Protomelas and compatible Aulonocara species. Avoid small peaceful community fish, slow or delicate species and fish with similar blue-and-orange male patterns that may trigger persistent rivalry. They are best kept in a carefully planned Malawi cichlid community rather than with African river fish, South American cichlids or highly aggressive mbuna. Keep one male with several females where possible, and avoid housing multiple territorial males in undersized aquariums.

Blueberry Canary OB Haps are maternal mouthbrooders. Spawning usually takes place over a flat stone or cleared patch of substrate, where the female picks up the fertilised eggs and broods them in her mouth for around three weeks. She should be given plenty of shelter and may be moved to a separate aquarium if other cichlids harass her. The fry can be raised on newly hatched brine shrimp, crushed flakes and suitably fine cichlid foods. As a selectively bred OB form, breeding results can be variable, and not every offspring will show the same blueberry or orange-blotched pattern.

Males are larger and develop much stronger blue coloration, often with more vivid orange or copper OB blotches and extended fin markings. Females are smaller and usually silver, grey or muted orange, with less intense blue; juveniles of both sexes can be difficult to distinguish.
