Great lil plecos to have. They dont get super huge. About 5-9'' max. I'd say on average about 6''. Wood is a must. They're mostly nocturnal. They may stay active looking for food a few times a day. I have one in a planted tank. They dont harm the plants if they're fed well and with variety. They maybe be a bit territorial within the same species. As is usually the case with most plecos. All in all. I enjoy having the Panaque albomaculatus (LDA31) and they will definantley get peoples attention. Their fins lengthen as they grow giving them a magestic look. Great and beautiful plecos to have in any tank.
