kevincanada Posted May 20 Share Posted May 20 Recently did a plant trim and decided to feed the guppy grass to the koi. Ive since lost three big ones due to some sort of constipation and I'm wondering if it's the plant. All of the small sized koi seem fine. Water is all good ph 7.5. No ammonia, nitrite , nitrate etc. And I've had the fish for years. Any ideas or experience with the plant? Thanks Kevin Link to comment Share on other sites More sharing options...
