I had a colt take over 1/3 of a 55 gallon. Those things are nuts. Even though I loved it I traded it out to some poor soul who said he wanted a big one. When we met to make the trade it had shrunkin in the bag to 1/5 it's size and he said thats the perfect size for my 20 gallon
! I made a quick gettaway lol. That was 7 years ago btw.
