If i put a pleco the same size as my oscars(4in) would it be ok if they were in a 4ft tank and it had lots of hidey holes would the pleco get bullied???
I agree, should be fine. Go for 'common' plecs though (HYpostomus Plecostomus) as they will keep up in size in relation to growth with the Oscars and they're very tough cookies!! I would consider gong for a larger tank and good external filtration eventually though because of potential water quality problems (both are very messy fish when bigger).
