is it possible to have a tank with purly plecos in, or as i suspect will they just start killing each other and freak out big time? 

well, i have a gold nugget plec and a common one in my tank, and suprisingly they get along fine and dont botheer the other fish, thats why i asked here, i might be intrested in starting a pleco tank.im no expert but i would guess you would need a pretty big tank to accomodate them all swimming around the bottom, but im not sure on how terretorial they are as ive only ever kept one at a time
