Conservazione: Amphilophus sp. 'xiloa fatlip' non inserita dalle organizzazioni internazionali di salvaguardia delle specie a rischio nella lista rossa. This species should be considered as vulnerable, since it is just found in the small crater Lake Xiloá, and apparently just in very small numbers.
