GreenPleco Original Plecostomus Plush plecos are 12in long (30cm) and pretty anatomically correct. Fins are where fins should be and they even have loricariid lips in front of the suckers. Hand them to an expert, and they could probably sex them for you. They come complete with suction cup on there mouth for mounting on pretty much anything a typical suction cup will adhere to. They’re made of synthetic acrylic fiber, so no animals were harmed in the making of, and they’re not recommended for children under three. But let’s be honest, most of us are not buying these for our kids, are we?
