For many aquarium inhabitants retreats are very important and only enable their species-appropriate attitude. Very popular are half coconut shells with an "entrance". Their planting with Anubias barteri var. nana increases the attractiveness of this natural product in the most beautiful way. The slow growing requires little care and can be well placed in a low light zone.
For cave breeders, such as Antenna Catfish and Purple Hawkfish, the Coco Cave offers an optimal breeding cave and good hiding places outside the breeding season.
