These are not mine, I spotted it in an LFS planted/display tank. I took the pics as I was browsing but forgot to ask and was unable to go back there, hence the post. But thanks for the insight, if I do decide to go for them I will follow your advise about keeping them in a group as I do have a lone ancistrus bristlenose plec so...One of my favorite fish you don't say if you have one or more of these, in my experience it can become slightly aggressive with other similarly shaped fish if kept on it's own, if space allows it's best to keep 3 or 4 together , they will develop a pecking order much like clown loach do. They are not solely herbivores , mine like meaty foods like blood worm and brine shrimp if given the opportunity. Your fish looks like a really nicely marked specimen
