Thanks guys... this helped out a lot i do remember now that it was a vieja of some sort. Is this guy really mean by nature b/c he really did eat the eyes out of my pleco. When i came home he was head 1st in the socket.... What type of pleco will be able to handle themselves with this guy,a red devil, marble catfish, venustus, and jack dempsy. tank is 100 gallons.. i was thinking a leopard cactus. Any thoughts...
