Max length : 3.5 cm SL 雄鱼/尚未辨别雌雄; (Ref. 122075); 3.2 cm SL (female)

Diagnosis: It is distinguished from all congeners by the combination of the following character states: caudal fin red with black posterior margin in males; flank and fins without dark spots in females; pre-dorsal length in males 57.5-61.4% of standard length; 3 + 12-14 gill-rakers on first branchial arch; 27-28 scales in longitudinal series; 14 series of scales around caudal peduncle; single longitudinal row of scales between anterior supraorbital series of neuromasts; anterior supraorbital series of neuromasts arranged in two sections, anterior section with one well-developed neuromast, posterior with two; three neuromasts in posterior supraorbital series; 26-27 caudal-fin rays; 28 vertebrae; second proximal radial of dorsal fin between neural spines of 10th and 12th vertebrae (Ref. 122075).
Found in temporary pools, swamps, ditches and small streams (Ref. 3788). Used for biological control of mosquitos (Ref. 3788). One of the so called 'annual fishes' which has eggs that can withstand seasonal droughts (Ref. 1739). A bottom spawner, 3-4 months incubation. Quite popular with aquarists; difficult to maintain in an aquarium (Ref. 27139).
发现于季节性的水池与溪流了。 (参考文献 3788) 用来了蚊子的生物学控制。 相当受水族业者的欢迎。 一那如此被称为有能抵抗季节性的乾旱的卵的 '一年一次的鱼'.(参考文献 1739) 底部产卵鱼， 3-4 个月孵育时间。 难以维持在一个水族馆.(参考文献 27139)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Thrives in seasonal rainwater pools. Spawns throughout the short breeding period until the pool dries up and all fish die except their drought-resistant eggs. Eggs go through a dry period of many weeks. When rain comes and pool fills, most of the eggs begin to develop and hatch within hours. Fry grow very fast. In only 6 to 8 weeks they are sexually mature and start breeding (Ref. 7062). In aquaria, males showed aggressive behavior toward each other. Females were being pushed down to the substratum by the males as a prelude to spawning.非洲: 桑吉巴的島的特有種, 東方的坦尚尼亞。
