| Remarks |
Specimens collected from sand banks near the shorelines of clearwater, slightly tea-stained streams. Found buried in coarse clear sand at the stream edge, at depths ranging from about 2 to at least 20 cm, in areas shaded by dense tropical rainforest (gallery forest). Waters with slow current, pH varying between 5.5 and 6.2, temperature between 27.5 and 28°C. Apparently fossorial by daylight. Its relatively short gut have no identifiable gut contents but suspected to feed on microscopic fauna like protozoa, rotifers and nematodes since it inhabits interstitial spaces among sand grains in nutrient-poor, clear- and backwater streams (Ref. 40443). |
