In their natural environment these Goodeids live in calm water regions (e.g. side areas) that have a substrate mainly consisting of rocks and mud. Algae exist in large number in these places.

In contrast to Ataeniobius toweri, which has the same area of distribution, Xenoophorus captivus withstands lower temperatures. However, the species can also be kept and bred at permanently high temperatures between 22 °C and 24 °C. The water parameters play a less important role.

Xenoophorus captivus are Goodeids with broad backs whose males have a large dorsal fin like the males of Ameca and Chapalichthys. The males reach approximately 5 cm, the females approximately 6 cm in length. The fish are peaceful and can be kept in a community tank. The males establish a ranking order that is not very pronounced. The ranking fights do not lead to injuries.

The feeding of these fish is easy. Flakes, frozen and live food are accepted, but the diet should be vegetarian to some extent. So Xenoophorus captivus can also be fed with scalded spinach, and algae, which are an additional source of food, should be left in the aquarium.

Breeding is not difficult. After approximately 8 weeks about 15 young are delivered. The newborn fish can have a size of 10-15 mm they are not vigorously pursued by the older fish. Due to the size of the young fish after birth raising them does not cause any big problems.

The highest number of offspring known to me was 47 living fry in one litter, which were released over a period of three days.
Within Poecilia Nederland a project has been launched which concerns itself with the preservation of this species.
