New Guppy Following Goldfish
I've recently added two new guppys to my aquarium. I already had 2 little comet goldfish (feeder fish). One of my new guppys is constantly following one of the goldfish. It's in no way aggressive behavior, but my poor goldfish seems super annoyed and can't get away from the guppy! What is going on here? I've never seen this behavior before. And the guppy doesn't do it to any other fish in the aquarium. Any advice??
