Kegel is a spawning cone for discus fish and angelfish. The plastic material the cone is made of makes the cone safe and user-friendly. The shape of the cone provides optimal stability even during most intensive spawning periods. This stability is ensured by the proportions of the cone, which, based on discus breeders experience, have been found the most appropriate in practice. Its rough surface makes the eggs laid by the discus attach to the cone more easily. As the cone is made of plastic, the disinfection, which should be carried out each time we put the cone in the aquarium, is easy. The cone should be positioned in the aquarium in such a way that the breeding pair have all-round access to it.
