Pond Chat / Strange behavior--possible predator?
« on: August 09, 2010, 08:28:58 AM »
My bigger Koi will not go into the deep end of the pond. It's like they hit a brick wall; they turn right around, even when I put some food into the feeding ring! The only thing that's different is I placed two small airstones in the deep end, but the small fish and goldfish don't mind that at all, and the big fish were interested in the bubbles a couple of days ago. Today, I found a dead baby fish in the skimmer; it was missing its head! I've never had any instance, that I could document, of cannabalism in the pond. Could some other animal or bird have visited the pond and scared the fish; if so, why, or how, would it only bite the head off a baby fish? Yipes!! I've not had any problem with predators, (knock on wood).
