Yes I do! My fish are so tame we pet them and they nibble on us all the time, some people pay for carp treatments in beauty salons, we get it for free :goldfish:
That's the hatchery, PVC pipe frame with garden mesh (fine stuff) stitched around. The "phase 2" one will probably accommodate them till they are big enough to sell/give away and keep our favorites. With 30+ fish, can't keep em all but don't want them to die! We have never done this before so not sure on anything, figuring it all out!
As for rain, we do have to watch out for overflow and we just do a little water change/release if it gets close. Our in ground one would overflow and there was nothing we could do about that though and my Matsuba (in particular) would end up beaching himself on the rocks because he would try to reach new "foods" when that happened. I like the knob release idea though! Thankfully our pond is semi-raised so even if the wall failed we would still have a 3 ft deep pond and not fish on the ground :neutral:
