Max length : 4.8 cm SL 雄魚/尚未辨別雌雄; (Ref. 44894); common length : 3.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 5259); 最大年齡: 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.
時常發現於中.植物沿著邊緣靜止的或流動緩慢的像小溪的沼澤，流域溝渠與洄水區的水域。 成魚生活於短暫存在而永久的棲息地。 被在第一個年中達成成熟而且嚴厲的要命在產卵之後不久的一種生命期短的魚。 當地表水蒸發夏天時的時候，可能地佔領短暫存在的水魚在小龍蝦洞穴中夏眠或者隱匿。 (參考文獻 44894) 可能一個每年產卵一次的種。 從八月到十月產卵。 類似它的西南方親戚 G. munda ，這種也是一個多隻產卵魚.(參考文獻 44894) 雌性在腐葉上堆積一些一天卵。 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。
