 Erratic Koi behaviour
Hi
Can anyone shed any light on a problem with one of my Koi. It appears to have a problem with its swimming control. It can be seen swimming around with its head out of the water, when i feed you can see it attempts to come to the feed but instead swims round and round in a tight circle, somersaulting at the same time. It does get to the food eventually. one other thing is it does not appear to be able lay in a horizontal position in the water but tends to sink tail first. Does anyone have any clues or has seen this problem before.: |
