Check out my two new additions to my 120gal freshwater. Both these fish were given to me by people whose tanks were too small for large fish.
(i don't have that problem)
the pleco is 12in and the Red Devil is about 5-6in
i also had a line on a 5in Jack Dempsey but just missed out. i would have liked to have the RD and the JD together, although territorial and aggressive i think the large tank i have would have been perfect for them both.
Also i got an 11in pleco im looking for a home...see my Classified thread
