I have 4 Tiger Oscars in my 240 with 12 Common plecos,3 Gold spotted sailfins, 3 Convicts, 3 Green Severums, and an RTC, Oscars are good with Plecos, forget the Adonis that's a pleco that can get to 39", the discus and a pleco not a good idea they are known to suck the slime of slow moving fish like discus, A similar pleco to yours would be a Gold spotted Sailfin. EBDJ look awesome and are great tankmates same with the Severums. L114 Leopard Cactus looks sharp too.
