fish near waterfall
Should I be concerned? I have a 2500 gallon pond with water lillies and
about a dozen koi (18") and a dozen goldfish. Lately I've noticed the koi are all hanging out under the waterfall. Nothing has changed - they never used to do this. They eat fine, and otherwise no issues. Is it posible they need more oxygen, or do they just like hanging out there? |

You may need to react straight away or you could loose them. Sorry, but that`s it. Keep the waterfall going in hot and/or thunderey weather. This takes the O2 out of the water. -- IAN. P.
