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.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 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.
在身體裡的深色色素胞, 形成一個從它的透明身體的兩邊是看得見的條紋。 沒有牙齒在齒骨與上頜骨前的。 長柄的大鐮刀-形狀的淚骨有一個連接前面的上顎軟骨組織的前面的刻面。
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).
標本採集自在清澈的水域的海岸線附近的沙子淺堆 , 些微茶沾染的溪流了。 發現在水流邊緣埋藏在粗糙的清澈沙子之中了, 在深度範圍從大約 2 到至少 20 公分, 在被密集的熱帶雨林 (長廊森林) 遮蔽的區域中. 水域且水流和緩的地方, 酸鹼度改變在 5.5 與 6.2之間, 在 27.5 與 28° C. 之間的溫度 顯然掘地白天時。 它的相當短消化道沒有可以確認的消化道內容，但是它被猜想自從它之後覓食微小的像原蟲的動物相, 輪蟲與線蟲類在營養物中居住於在沙子穀粒之中的間質空間-少量的, 清澈的水域與迴流水溪流.(參考文獻 40443)
