Acarichthys heckelii requires an aquarium of at least 1.80 meters. Decorate the aquarium with stones and driftwood so that caves are created as a shelter. The soil must consist of sand that they can dig in. Use hardy plants, which are usually left alone. To secure them firmly, you can anchor them in a flower pot in the substrate. With the use of floating plants, the lighting can be slightly dimmed, floating plants such as Ceratopteris thalictriodes will certainly be appreciated. It is advisable to change water regularly.

Both live food and frozen food, such as shrimps, mussels and krill, can be given as food. They even appreciate a fatty earthworm. Dry food is hardly accepted.
It is a fairly calm fish in which the adult animals, like most other Eartheaters, are relatively tolerant of each other. Acarichthys heckelii can be kept together with other large peaceful cichlids, smaller fish are seen as food. They can form a large territory, it is a real construction worker and likes to dig in the soil.
Breeding Acarichthys heckelii
Breeding Acarichthys heckelii is quite easy. Contrary to popular belief, this is not a mouth brooder, but they deposit the eggs against the ceiling of a cave. If you want to breed with these fish then a cave is necessary, make sure that the entrance is so large that 1 fish can completely block the entrance. A good tip: use a glass jar and cover it with driftwood. The cave should not be completely dark.
Once the eggs have been deposited, the female remains in the burrow until the eggs hatch after 3 days. All the while, the male stands guard at the entrance. The first 3 days after hatching, the fry swim around in the cave. Another 3 days later they swim freely through the aquarium. As soon as they hatch, you can immediately feed them with freshly hatched brine shrimp, egg yolks and crushed flake food.
