Only in this case, she can feel free, showing all the features of behavior.
If this is not possible, then non-aggressive fish from the family of cichlids, such as aulonocara, should become neighbors. In general, any Malawian fish will do. Particularly interesting is the blue dolphin with yellow labidochromis.

The blue dolphin Cyrtocara moorii (formerly Haplochromis moorii) is an unusual aquarium cichlid originally from Lake Malawi in Africa. It is popular among fans of cichlids, primarily for coloring, as well as for the unusual body shape with a large fat cone.
At the same time, blue dolphins are quite rather big aquarium fish, and can reach a size of 25 cm or more. Sufficient peaceful, but males are aggressive towards each other, and it is better to keep them in a harem, from one male and three or four females.
Such a harem lives on its territory, which is carefully guarded only during spawning, at other times remaining more tolerant.
Keep blue dolphins is simple enough, provided that they live in a spacious aquarium, the water in it is stable and clean, and it is decorated correctly. It is best to design in the form of a biotope, with sand as a soil, a large number of stones and various shelters, and free space sufficient for swimming.
Blue dolphins are polygamous fish, form a family consisting of a male and several females. One male can be useful 3-6 females.
Since the sex of dolphins is difficult to determine, the best way to pick up such a harem is to buy from 10 fry and grow them together. Fry become sexually mature with a body length of 12-15 cm, and then they are separated.
The male chooses a place for laying, as a rule, it is a smooth stone or digs a hole for caviar in the ground. After that, spawning begins and the male invites the female and she lays her eggs, and the male fertilizes her.
Since the fish are carrying caviar in the mouth, the female takes it for incubation. The female bears 20 to 90 eggs, and bears them for two to three weeks. The period depends on the temperature of the water and the environment.
After hatching, the female also hides the fry in the mouth at night or when they are in danger. Starter feed for fry – naupilii artemia.
Fry grows very slowly.

The female lays caviar on the previously cleaned surface of the stone or in the hole, which the male digs in the ground. She bears fertilized eggs in her mouth.
All this time – 21 days – the female does not eat, as a result, it loses its strength.
Eggs are removed from the female’s mouth and placed in a separate container. For the normal development of “dolphin offspring” it is necessary to provide in the incubator soft lighting and the presence of fresh running water.
Fry born to night prefer to spend in the mouth of a female. Both parents protect offspring.
