I'm new to garden ponds so please forgive my ignorance. I have a 1,200 gallon freeform pond that I constructed last summer. It has 2 koi, 2 shubunkins and 4 goldfish. Last week one of the shubunkins was being aggressively chased by the other shubunkin and the goldfish. I removed her from the pond, thinking that she might be sick or ready to lay eggs. After a week in confinement in a small container, she is still alive. This morning, I noticed some green bubbles on the surface of the container. Are they shubunkin eggs, green bubble algae, or just bubbles? See attached photo. Thanks.
