Bumblebee Cichlid care guide
Bumblebee Cichlid (Pseudotropheus crabro) — minimum tank 350 L, temperature 24-27 °C, pH 7.8-8.6.
Overview
Pseudotropheus crabro ("Bumblebee Cichlid") is a Lake Malawi mbuna distinguished by bold black and yellow vertical bars. The species has the unusual habit of cleaning parasites from large kampango catfish (Bagrus meridionalis) in the wild. Adults reach about 15 cm.
Taxonomy
- Family: Cichlidae
- Genus: Pseudotropheus
- Scientific name: Pseudotropheus crabro
- Common synonyms: Crabro, Hornet Cichlid
Habitat
Endemic to the rocky shore (mbuna zone) of Lake Malawi in the African Rift Valley, where it lives over wave-washed boulder slopes. The lake is exceptionally hard and alkaline — pH 7.8-8.6, KH 6-15 — and warm year round. The species is highly site-attached and territorial males defend small rock caves.
Tank requirements
- Minimum tank volume: 350 L (92.5 US gal)
- Adult size: 12-15 cm
- Temperature: 24-27 °C (75-81 °F)
- pH: 7.8-8.6
- GH: 10-20 °dGH
- Water flow: medium
- Lifespan: 6-10 years
Diet
In the wild it grazes the aufwuchs layer of algae, biofilm and associated micro-invertebrates that coats the rocks. In aquaria a vegetable-rich diet of spirulina and algae-based cichlid pellets, blanched vegetables and occasional frozen brine shrimp is appropriate; high-protein foods such as bloodworm should be avoided to prevent "Malawi bloat".
Compatibility
Aggressive and territorial; best kept in a large mbuna community with several other rock-dwelling species so that aggression is dispersed. A typical stocking is one male to several females (1:3-4). Avoid mixing with very different lake faunas (e.g., New World cichlids) and with similar-coloured congeners that may hybridise.
Breeding
A polygamous maternal mouthbrooder. The male defends a small rock territory, displays to passing females and entices each to spawn on a flat surface; the female collects the eggs into her mouth immediately and incubates them for about three weeks before releasing free-swimming fry.
Conservation status
IUCN Red List: see species page. The Lake Malawi cichlid radiation has been intensively assessed; most mbuna are evaluated and many are categorised Least Concern, though species with restricted ranges along single sub-shores are more vulnerable.
