I have a pond its about i think like 500 gallons or more..Its semi filtered I beleive (it has a waterfall) I can put pics up if wanted. Right now its only inhabited but a sunfish and 3-4 goldfish. I was wondering if I could heat it up and put some more exotic fish in there. Maybe a shark(bamboo) 
.. Jk that would require much effort.. IF you have any suggestiions on coldwater stocking or warmwater it would be helpful. Also I actually am not completely sure of the size.. With my perception it could be from 200-1000... 
Its like 3 and a hallf feet deep and like 5 long and maybe 7 wide.. but im basically just guessing.. Ill post pics
