Neolamprologus multifasciatus, or for short, Multies are a special type of cichlid for many reasons. The first reason is they are shell-dwellers, or Shellies, which means that they live and breed in shells. In the wild, Shell Dweller Cichlids live on the bottom of Lake Tanganyika in Africa. They colonize the thousands of Neothauma snail shells and form territories of their own shells and live, sleep, and breed inside these shells. They mainly stay near these shells, and on the bottom, so it is best to get a short, long tank.
The second special thing about Multies is that they are the smallest cichlid in the world, the male’s maximum size is 1.5 to 2 inches, and the female’s maximum size is only around .75 to 1 inch long! This means that they are easier to keep in smaller aquariums.
For a tank setup, you can use almost any tank, preferably a 10 gallon, and if possible, go for a longer tank, since they use mainly bottom space. These fish are big diggers, so definitely have either sand or very fine gravel if you want to see this behavior. Also, they should have about 2-6 shells per fish, so they can choose which ones they want. You can use Apple snail, escargot, or practically any other type of shell you want, or also PVC elbows with caps can work fine too.
