i read somewhere on here that common plecos don't go with goldies, they only said "fancies" so can i put mines with my comets?
heres pictures:

the big guy is only 11 to 12 inches long

that's a big pleco alright, dunno what kind but looks kinda menacing i wouldnt put it with the goldies though, even comets

awwww, he's not that agressive......

yeah mine wasnt aggressive till one day he took down my 6" goldfish and killed him

wat!?! sorry bout ur goldfish


o forgot my guy has huge teeth.......

yours looks like the sailfin plec which can grow to 18 inches+ depending on tank size.
As koko said they will take down a fish as these need meat in the diet once mature. They are fast swimmers and can easily grab hold of a larger fish and they have huge suction power and will literally rasp the goldfish clean of its slime coat first and then the meat.
Dont put it with goldfish.

ahh! im getting this foot long pleco...im looking for abig rubbermaid to keep him in...thats what im afraid of...those teeth and suckers! :

the guy ripped my fish net and now i have to sow it back........
