Speaking of koi

Koi ponders have learned the hard way that their fish tear up every plant they try to grow in the pond with them. The plant debris clogs up filters and pumps, and even skimmers. It makes a big mess. Koi owners have realized that they had to make a choice between the two and apparently decided on the fish. Most of the koi owners I know have two ponds, one for fish and one for the plants they started with. Koi aren't prima donnas, they are terribly destructive. If they weren't beautiful, and filled with personality, we wouldn't even bother with them at all.
