Etymology: Lithoxus: Greek, lithos = stone + Greek, oxys = sharp (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical

Max length : 7.0 cm SL male/unsexed; (Ref. 36713)
Inhabits stony rivulets (Ref. 6868); has been collected in little forest tributaries (3 to 4 m wide) with shallow depth, rocky bottom, strong current, often with cascades. Likewise, during the dry season, it has been found in a split brook with very little water input, where only 2 species of Rivulus (R. igneus and R. cladophorus were present, thus suggesting that Lithoxus is a pioneer species which is capable of colonizing difficult environments which are nutritionally poor (Ref. 35381).
