Max length : 4.8 cm SL 雄鱼/尚未辨别雌雄; (Ref. 44894); common length : 3.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 5259); 最大年龄: 1.00 年 (Ref. 44894)
Facultative air-breathing (Ref. 126274); Frequently found among vegetation along the edge of still or slow-running waters like swamps, drainage ditches and backwaters of creeks. Adults live in both ephemeral and permanent habitats. A short-lived fish, reaching maturity in the first year of life and perishing shortly after spawning. Fish occupying ephemeral water possibly aestivate or shelter in crayfish burrows when surface water evaporates during summer (Ref. 44894). Probably an annual species. Spawn from July to October. Like its southwestern relative G. munda, this species is also a multiple spawner (Ref. 44894). Females deposit a few eggs per day on leaf litter. Eggs hatch after 10-17 days at 16°-21°C. Scanty information on diet: captive specimens eat small invertebrates and filamentous algae.
时常发现于中了植物沿着边缘静止的或流动缓慢的像小溪的沼泽，流域沟渠与洄水区的水域。 住短暂存在而永久的栖息地。 被在第一个年中达成成熟而且严厉的要命在产卵之后不久的一种生命期短的鱼。 当地表水蒸发夏天时的时候，可能地占领短暂存在的水鱼在小龙虾洞穴中夏眠或者隐匿。 (参考文献 44894) 可能一个每年产卵一次的种。 从八月到十月产卵。 类似它的西南方亲戚 G. munda ，这种也是一个多只产卵鱼.(参考文献 44894) 在腐叶上每天产一些卵。 卵在 16 °-21 °C. 在 10-17 天之後孵化 缺乏的關於食性的資訊: 捕獲的標本吃小型無脊椎動物與菌絲藻。
