I have a koi pond and I love it,but fancy goldfish suck.Thanks Darren.
Yeah, goldfish are the worst. I don't see the appeal. Maybe a big outdoor koi pond, if I lived in the south. But even then I'd probably do a "cichlid pond".
I think even with the swords my tank still looks reasonably natural, and I'll probably remove one to thin it out a bit. Five is a bit much. But the fish and the family both love them, so they stay.
