Leptophilypnion is a genus of tiny fishes in the family Eleotridaeendemic to the Amazon Basin in South America. At less than 1 cm (0.4 in) in standard length they are the smallest sleeper gobies and among the smallest fish.[2] The larger Microphilypnus sleeper gobies are also found in the Amazon,[3] and sometimes occur together with Leptophilypnion.[2] The bottom-dwelling Leptophilypnion are typically found in shallow, stagnant or slow-flowing water among soft debris, leaf-litter or water plants.[2]
