|Scientific Name||Ammoglanis pulex de Pinna & Winemiller, 2000|
|Type Locality||Río Paria Grande at bridge on road between Pto. Ayacucho and Samariapo (5°23'N, 67°37'W), Estado Amazonas, Venezuela.|
|Etymology||The specific epithet pulex means flea in Latin, in reference to the minute size of the species. A noun in apposition.|
|Size||14mm or 0.6" SL. Find near, nearer or same sized spp.|
|Identification||Ammoglanis is a genus of diminutive slender trichomycterids. Its original description identified three unique traits for the genus: 1) slender quadrate, its maximum depth about 30% of length of its main axis; 2) expanded anterior tip of interopercle; and 3) premaxilla located posterior to mesethmoid cornu.
Ammoglanis pulex can be identified by possessing all of the following traits: 1) dark chromatophores in interior of the body, forming a banded pattern visible from both sides by transparency in the living fish; 2) lack of dentary teeth; 3) scythe-shaped lacrimal with an anterior facet articulating with the anterior palatine cartilage; and 4) lack of premaxillary teeth.

|pH||5.5 - 6.2|
|Temperature||27.5-28.0°C or 81.5-82.4°F (Show species within this range)|
|Other Parameters||In nature, found along stream segments with slow current. Temperature and pH values listed are those recorded in the wild when the species was described.|
|Feeding||The mouthparts of this species indicates it is a nonparasitic trichomycterid. Likely, it feeds on microscopic fauna (e.g. protozoa, rotifers, nematodes) living between sand grains in the stream bed.|
|Furniture||In the wild, collected in sand banks near the shorelines of clearwater, slightly tea-stained, streams. Fish are found buried in coarse clear sand at the stream edge, at depths ranging from approximately 2 to 20 cm. The locations where fish were found were always shaded by dense tropical rain forest (gallery forest).|
|Compatibility||In nature, this species is found with a variety of other fish, including Astyanax cf. polylepis, Bryconaps sp., Capella sp., Hyphessobrycon sp., unidentified Characidae, and Aequidens diadeas. This is not to say that A. pulex is compatible with all of these, but merely that they are found together.|
