The Demasoni Cichlid, scientific name Pseudotropheus demasoni is an especially sharp-looking African cichlid. It comes from Lake Malawi and is a more modern addition to the aquarium hobby.
It was first described and introduced into the hobby in 1994 by Ad Konings and was named after his good friend Laif Denison. It’s also identified by the common names Demasoni Cichlid and Midnight Demasoni.
In this article, I am going to talk about Demasoni Cichlid fry, size, tankmates, for sale, female, care, male vs female, breeding, tank size, max size, etc.

Demasoni Cichlid Overview
It is a dwarf Mbuna that solely reaches about 2 half to three inches (6.4 to 7.6 cm) in size. It’s a fair cichlid that has a very inquisitive nature with lots of personality and spunk.

Within the proper setup it can simply adapt to ready meals, breed readily, and the juveniles are easy to lift as well.
Aquarium Hardiness: Moderately Difficult
Aquarist Experience Stage: Intermediate
Demasoni Cichlid Habitat
The demasoni cichlid often resides in Africa. It’s present in nice numbers in Lake Malawi close to Pombo Rocks and the Ndumbi reef close to the Tanzanian coast.

The streams that circulate into Lake Malawi have a high mineral content. This together with evaporation has resulted in alkaline water that’s extremely mineralized.
Lake Malawi is thought for its clarity and stability so far as pH and different water chemistries. It’s easy to see why it is very important to watch tank parameters with all Lake Malawi fish.
Rift lake cichlids want hard alkaline water however aren’t found in brackish waters. Salt is usually used as a buffering agent to extend the water’s carbonate hardness.
