While they are social and a schooling fish, they continue to choose the same companion for multiple spawning periods. Unlike most other species who leave their fry (fish babies) to fend for themselves, discus fish act more like marine mammals in how they provide for their young! How many fry can you spot in this video? | Mystic Aquarium | Facebook
