Nice shots Phoenix44. Just a slight correction. Many plecos have teeth, only Panaques have short spoon-shaped teeth (ie wider at tips than base) so they can rasp wood, bark, and algal biofilm. Goldie plecos (and other Scobinancistrus), which are closely related also spoon-shaped teeth but they are much longer and narrower than in Panaques, and are thought to be for eating molluscs (i.e. snails, etc.)
