I have a garden pond with goldfish and koi. I’ve started watching them. It seems if they are active the crappie bite is decent. If the are suspended not moving around the crappie bite is slow.
we got "A" goldfish in the resting aquarium that typically houses other critters , it is sometimes inactive as well , but a mere drop of food scent in the water makes it lose its little goldfish mind in a quick second .
