Hello fellow ponders! Checking in from the northeast foothills of the San Gabriel mountains in SoCal, ~ 5000 ft. elevation. This is more of a re-introdution, as I posted on here several years ago. The last year or two have been rough (divorce) but I still have my pond and it's doing well, and so am I. It's 16x10x3 feet deep. I have 3 generic koi from petsmart, about 8 years old. I think they love having this big pond to themselves, but I'd like to get some goldfish or a couple more koi. I'm just afraid the koi I have will eat the new koi. They are big! I'll search for older threads for advice on how to do this, but please chime in here if you'd like to advise. Thx!
