Conservazione: Apistogramma pedunculata è valutata dalle organizzazioni internazionali di salvaguardia delle specie a rischio come (NT) Quasi Minacciata (2019). Even though it has a wide extent of occurrence, the area of occupancy of this species is small (36 km2). It only occurs in two rivers, which are very far from each other, the subpopulation in the Caura River is threatened because of log extraction and water pollution related to gold mining. There are three illegal gold mines within the distribution area of the population within the Lower Caura River, affecting this subpopulation through habitat loss and degradation (Echeverria, 2019).
