Adonis Pleco "Acanthicus adonis"

Common names: Polka Dot Lyre Tail Pleco, Adonis Plecostomus.  The coloration of a juvenile is much different than a full grown adult. The adonis pleco as a juvenile is dark brown to black with numerous white beautiful spots which fade away as this fish grows and are fewer in number when full grown. This is a beautiful fish when small. Once they get larger than about 20 cm they lose coloration.

Described from the lower rio Tocantins near the city of Cametá, Pará state, northern Brazil and occurs throughout the lower part of that system. Although definitive details are lacking, it’s also thought to range throughout much of the Amazon basin with similar-looking fishes being exported from as far afield as Peru.
