ive kept scobinancistrus aureatus before. predominantly carnivore, just fed bloodworms and prawns and some veg now and again to keep it varied. they are a beautiful fish, and as for plecos, when they got a bit bigger they were reasonably active even in the day. give it some driftwood for sure, and obviously some hideouts. keep the skins on the prawns cause they'll eat this before the flesh, and if you keep em well fed, sometimes they wont even bother chowing on the flesh much at all, so you gotta take out the uneaten stuff before it fouls the water. o and they took sinking carnivore pellets too. beautiful pleco
