Bogwood is essential - both for dietary reasons and because it seems to be the Royal Pleco's preferred hide-out - although any suitably sized dark refuge will be utilized. When larger, Royal Plecos will re-arrange the tank to their own liking; ensure rocks are well secured and cannot be toppled against the glass.
Territorial with conspecifics and other similarly sized catfish although otherwise peaceful with smaller fish. This fish can be a fussy feeder and only once it is feeding well should be mixed with large, boisterous fish.
