Updating this inquiry about missing or dead koi...my friend in HPP had about 100 small gold fish in her outdoor pond with several larger koi and all but about 10 or 12 of the gold fish disappeared apparently overnight. That's quite a bit of small fish! At least several dozen!
She is wondering what possibly could have done that. One of the larger koi has a smaller than dime-size white spot on his nose that is perfectly round like a tumor but is a bit ragged 3-dimensionally. I mentioned that the night sky has been particularly bright over the past week (due to the full moon and unusually cloudless skies) and suggested birds, hawks, owls. She has dogs loose in her yard at night and mongoose are daylight predators.
Also, the remaining fish seem lethargic and several kept hanging out by a bit of a crevice in the pond's rock wall. What do you all think is going on here? No one has used any chemical spray nearby. Surely the vog down Kaloli Blvd. hasn't been strong enough to acidify her pond, do you think? And does anyone know what ph of water is ideal for pond fish?
Thanks for any advice...[8D]
