I finally got my hands on one yesterday... BUT !! when i was looking around at different sites .. at goldfishconnections they said you should never put any kind of pleco in the tank with goldfish !!! i was wondering, why does the rubbernose pleco any different from common pleco and in what ways its different so that its safe to put in goldie tank

Rubbernose plecos are pretty much guarented safe. They stay small(3 inches) and they dont usually get agressive. Common plecos can grow to sizes of 18 inches, and once they get past about 4 inches, they start turning carniviours.

so .. rubbernose pleco does not turn into a carnivore after turning into an adult? and you mean that they are much friendlier as of a frd in the tank with the goldfishes... i never really understand why rubbernose pleco is compatible but now its making more sense ^^

Yup, thats exactly right
