Care basics

Demasoni are small, striped blue mbuna with big attitudes. They look stunning in a group, but a few demasoni in a tank often means one bullying the rest.

Plan a heavily rocked tank with lots of caves, keep a large group, and do not mix them with other blue barred mbuna that look similar.
