Deep Water Hap care guide

Deep Water Hap (Placidochromis electra) — minimum tank 400 L, temperature 24-27 °C, pH 7.8-8.6.

Overview

Placidochromis electra ("Deep Water Hap") is a Lake Malawi haplochromine in which adult males display a metallic blue body and head with a contrasting black bar from the eye to the gill cover. Adults reach about 18 cm. The species is found over sandy substrates at deeper levels of the lake.

Taxonomy

  • Family: Cichlidae
  • Genus: Placidochromis
  • Scientific name: Placidochromis electra
  • Common synonyms: Electra

Habitat

Endemic to Lake Malawi, where it inhabits sandy bays, sediment-rich flats and the sand-rock interface of the open lake. The water is hard and alkaline (pH 7.8-8.6, KH 6-15) and warm year round; large adults forage across open sand and through rock outcrops.

Tank requirements

  • Minimum tank volume: 400 L (105.7 US gal)
  • Adult size: 14-18 cm
  • Temperature: 24-27 °C (75-81 °F)
  • pH: 7.8-8.6
  • GH: 10-20 °dGH
  • Water flow: medium
  • Lifespan: 8-12 years

Diet

In the wild a carnivore or specialised feeder depending on species — many haps eat small fish, invertebrates or sift sand for hidden prey. In aquaria a moderate-protein cichlid pellet supplemented with frozen krill, mysis and chopped earthworm maintains condition and colour; vegetable matter is not the main component as it is for mbuna.

Compatibility

Less aggressive but larger than mbuna; best kept in spacious 350+ L tanks with one male and several females, alongside other peaceful Malawi haps and peacocks. Avoid mixing with rock-dwelling mbuna, whose constant aggression suppresses these larger fish, and avoid similar-coloured congeners to prevent hybridisation.

Breeding

A polygamous maternal mouthbrooder. The male defends a sand "scrape" or a small territory near a rock, displays his nuptial colours and entices females to spawn; the female collects the eggs into her mouth and incubates them for about three weeks before releasing fry.

Conservation status

IUCN Red List: see species page. Most haps are widely distributed in Lake Malawi and assessed as Least Concern; localised forms with narrow ranges are more vulnerable to environmental change.
