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.

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).
