Pindani / Socolofi (Pseudotropheus socolofi) Breeding Guide

Breeding Pseudotropheus socolofi: sexing two similar sexes by egg spots and fins, harem setup, a 3-4 week mouthbrooding hold and rearing fry.

Overview

Pseudotropheus socolofi, the Pindani or Powder Blue, is a mbuna endemic to Lake Malawi, occurring along the Mozambique coast between Cobue and Tumbi Point. Males reach about 11.5 cm and females about 10 cm. It is a maternal mouthbrooder and one of the more reliable mbuna to spawn.

Sexing

The sexes are hard to tell apart because both display the same solid powder-blue colour. Males carry larger and more intense egg spots on the anal fin and usually have longer pelvic fins, but behaviour is the most reliable cue, as males show territorial aggression toward females and other fish.

Conditioning

Condition the group on a high-quality diet composed mainly of vegetable matter. Keep the water alkaline and stable, with a pH of 8.2-8.5 and a temperature of about 25-27 degrees Celsius (77-80 degrees Fahrenheit) during the breeding period.

Breeding Setup

An aquarium of around 90 cm (a 36-inch tank) furnished with rockwork, flat stones and open substrate provides spawning sites. Use a harem of one male and at least three females so that the male's attention is spread among several fish.

Spawning Behavior & Trigger

The male displays intense colour around his chosen spawning site and can be quite aggressive in his pursuits. The female lays her eggs and takes them into her mouth, where they are fertilised via the male's anal-fin egg spots.

Egg & Fry Care

The female carries the eggs for around three to four weeks before releasing the free-swimming fry, refusing food throughout. The fry are large enough to take brine shrimp nauplii, microworm and powdered dried foods from birth.

Common Challenges

Because both sexes look alike, building a balanced harem can take patience and observation of fin shape and behaviour; the longer pelvic fins and the larger, more intense anal-fin egg spots of the male are the most useful physical cues. As with other mbuna, a stressed holding female may abort the brood, and only one Pseudotropheus species should share a tank to keep the fry pure. Being one of the more reliable mbuna to spawn, a well-conditioned harem in stable water will usually produce broods without any special trigger beyond good feeding.
