Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Forms large spawning aggregations. A female spawns with one or a few males, which press the female against the substratum and eggs are released. These movements attract other individuals to start spawning. The aggregations disperse after about 20-60 seconds and many form again several times. Deposits adhesive eggs (Ref. 59043).歐洲: 葡萄牙。 在伯恩公約的附錄 3 中 (受保育的動物群).
