why would they sell me a giant pleco.I told them I wanted a small one and that I only had a 2.5g tank. DO people who work in fish stores know anything? In my profession that would be like selling a mastiff pup to someone in a studio apartment. (which could be ok btw, since they turn to couch potatoes in adulthood . Ok off the soapbox) Any-hoo I am fishless cycling my new 29g tank and I will more than likely move him to it once its already, will that work?
