The present invention relates to incubation and cultivation of young aquarium fishes. To this end, an internal vertical partition, which is detachable when incubation care is required for adult female fishes reaching an incubation period, is mounted to a water tank so as to separate the adult female fishes from other adult fishes, thereby giving rise to safe and successful incubation by the adult female fishes. After termination of the incubation, by moving the adult female fishes to the other side, it is possible to protect the young fishes from being eaten, since the aquarium fishes tend to eat the young fishes which are born from the adult female fishes.COPYRIGHT KIPO 2017본 발명은 관상어 치어육성과 부화에 관한 것으로, 부화기에 이른 암컷 성어가 부화가 필요할 경우에 탈부착 가능한 내부 수직 칸막이로 수조에 장착하여 다른 성어로부터 암컷 성어를 분리하여 암컷이 안전하게 부화에 성공하도록 하며 부화가 끝난 후에는 암컷 성어를 다른 쪽으로 이동시켜 관성어의 특징인 자기가 부화한 치어를 잡어먹는 속성으로부터 치어들을 보호한다.
