Todd/Geoff/Nick/Moon/Mystery & killer rain sleuths - even if the hypolimnion (cooler bottom water) of the pond wasnt anaerobic yet, there could have been a lot of hydrogen sulfide H2S down in the detritus layer, that got churned up by a rain-induced turn-over. You can watch fish stress out even in a well aerated aquarium if you stir up deep dirty gravel full of aged fish poop (and smell that H2S). Its very toxic stuff, but oxidizes or dissipates ??? pretty quick after mixing in aerated water.
