My brother has a guppy that's been around for 6 years! lol he wants a new fish, but this darn guppy just refuses to die! which from my POV is a good thing
we have a peppered cory couple (M&f) who we've had for 5 yrs now, they've survived alot- massive tank rupture,auto feeder failure ( no food for 2 weeks) to name a few! we love them-tough little guys.
