Occurs in rivers with tidal influence. Found in association with submerged aquatic macrophytes, primarily the eelgrass Zostera capensis (Ref. 26174). Sympatric with Syngnathus acus in the eelgrass beds (Ref. 26174). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
出现于受潮汐影响的河川。 发现于邻近水下的水生大型植物, 主要地鳗草 Zostera capensis.(参考文献 26174) 在鳗草床与 Syngnathus acus 重迭分布了。 (参考文献 26174) 卵胎生的.(参考文献 205) 雄鱼带卵在一个孵卵袋是在尾部下面发现.(参考文献 205)
