Etymology: Ammoglanis: Greek, ammos = sand + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish. Glanis was the sacred spirit of springs in the town of Glanum and there was the Glanicae, a triad of local mother goddesses (Ref. 45335); pulex: Named for its small size ('pulex' meaning flea); noun in apposition.

Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Σπόνδυλοι: 30 - 31. Dark chromatophores inside the body, forming a banded pattern visible from both sides of its transparent body. No teeth on dentary and premaxillary. Scythe-shaped lacrimal with an anterior facet articulating with the anterior palatine cartilage.
Body shape (shape guide): elongated.
Specimens collected from sand banks near the shorelines of clear water, 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 it is suspected to feed on microscopic fauna like protozoa, rotifers and nematodes since it inhabits interstitial spaces among sand grains in nutrient-poor, clear-water and backwater streams (Ref. 40443).
