if I had a 500 gallon tank I would probably import a colony really rare malawi cichlid and just let them go for a year. I mean only add 10 or so fish. I would like to really replicate the natural environment by not overcrowding.
but I'd probably get sick of looking at the same fish or being overrun by fry so I'd most likely make it a 500 gal reef tank and pay someone to look after it.
