Found mainly in the littoral zone, occurring exclusively over stone or sand. Spawns near shore at depths not exceeding 1.5 m, from the end of May to mid July. About 600 eggs are deposited under stones during spawning. Spent females move away to deeper waters (10-30m); males guard the eggs until the fry stage (Ref. 2058).
主要发现于专门地在石头或沙子之上被出现的海滨的区域了。 产卵近岸在深度不超过 1.5 公尺，七月中旬的从五月底。 大约 600个卵被在产卵的时候在石头下面存放。 产卵的母鱼移开到较深的水域;(10-30 公尺) 雄性保卫卵直到鱼苗阶段。 (参考文献 2058)
