Hello, I have been on these forums for a very long time and anytime I see someone consider or buy a common pleco, I immediately say that it needs a minimum of 75 gallons. I kind of have a dilema right now. I am currently dog sitting for my brother's boss and I noticed they have a fish tank. A 20 gallon with two skirt tetras and a 6 inch common pleco. I was about to say something but then they said they are trying to get rid of it, tank and all. My dad wont let me take the tank but the fish I can have if I want. I might take the skirt tetras or give them to a friend and then rehome the pleco to someone else who can care for it. I kind of got attached to the pleco, I usually dont care for them, but this 6 inch pleco is just beautiful and his fins are always out and flowing. I'm wondering, I know they need a minimum of 75 gallons, but, is it possible I can keep this guy in my 48 gallon tank? I am also kind of unsure if he is a common pleco, I thought he was at first but then I noticed little features that might be different. His belly is full of really white dashes and markings. And the dashes and dots on his body are kind of goldish in color. His mouth also has a little bit of length to it, as in its not completely rounded. Help please?
