Etymology: Crenicichla: Latin, crenulatus = cut, clipped + Greek, kichle = wrasse (Ref. 45335); tapii: The specific name tapii is a Guaraní word (tapií), means tapir (Tapirus), in reference to the subterminal mouth and the concave head of the species associated with its grazing semi-herbivorous
mode of feeding similar to that of the tapir but highly untypical for the generally predatory Crenicichla.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical
South America: Lower Iguazú River basin above the Iguazú Falls in Argentina. Distributional range extends upstream of the Misiones Province, Argentina into the neighboring state of Paraná, Brazil.

Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 104794)
Relatively common only in the main channel of the Iguazú River, where they can be observed in schools on the flat-rock substrate from the walkways over the river grazing on periphyton. Always encountered in direct association with flat slab-like exposed rocky bottoms with epiphyte growths, never above gravel or soft sediment-covered bottoms. Grazes on periphyton (Ref. 104794).
