Biologi     Daftar kata (contoh epibenthic)

Facultative air-breathing (Ref. 126274); This species was captured from small streams to the main channel of rivers within Paraguayan territory. The arroyo Laguna Penayo is a stream with about 20 m width and 0.5 m deep, with very slight to stagnant current, turbid water, and substrate composed mainly of clay. An unnamed stream tributary from the río Apa, about 25 m width and 1 m deep, with stagnant current, dark brown, very turbid water, and substrate composed by sand, rocks and trunks. The río Araguay-Guazú, is relatively small river with about 35 m width and 1 m deep, moderate current, turbid water, and substrate composed mainly by sand. The río Jejuí-Guazú is a small river with brown semi transparent water, and substrate composed mainly by sand, gravel and leaf heaps. Another small, unnamed stream tributary from the río Paraguay has light brown water, and substrate composed mainly by sand. Most sites presented some degree of anthropogenic impact (Ref. 123578).

Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva

The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. Only then the female swims to a suitable spot, where she attaches the very sticky eggs. The pair repeats this process until about 100 eggs have been fertilized and attached (Ref. 1672).
