Found to exhibit parasitic traits (Ref. 6868). Inhabits rivers with sandy to muddy bottom.
Forages both during the day and at night seeks the gill chambers of larger fishes, especially catfishes. Enters and leaves the gill chamber during the host's ventilating movements: feeds on blood drawn from the gill filaments and may stay in the gill chamber for 1-3 min; when gorged with blood, moves to the bottom and buries itself in the sand. A single large catfish tethered on the river bank may feed thousand of these parasitic catfish over a period of up to 6 hours. Two females, 1.8 cm TL, caught in January (wet season) had about 150 mature oocytes each, and one male 2.0 cm TL had well-developed testes. Large numbers of this fish may kill fishes tethered by fishermen (Ref. 40386).
发现展现寄生的特徵。 (参考文献 6868) 栖息于河底部为砂质或泥质的地方。
觅食两者在白天期间而在夜晚寻找较大的鱼的鳃室, 尤其鲶鱼。 在寄主的换气运动的时候进入而且离开鳃室: 吃被取自鳃丝的血液而且可能停留在鳃室中在 1-3 分钟之中; 当吃饱血液, 移动到底部而且掩藏于沙子中。 在河岸上被链栓的一个大的鲶鱼可能吃成千的这些个寄生的鲶鱼超过 6 小时。 二个雌性 , 1.8 公分TL,在有大约 150个成熟的卵母细胞的一月 (湿季) 捕获了每个, 与一个雄鱼 2.0 公分TL 有了发展良好的睾丸。 许多的这一个鱼可能杀被渔夫链栓的鱼。 (参考文献 40386)
