koi
after deciding the pool was little used and a pain to maintain now that the kids are grown
we put some feeder goldfish in it
mostly to eat the mosquitoes wigglers
they quickly grew huge and are spawning
without being fed anything but the bugs in the pool + frog eggs and tadpoles
so we got 10 Koi from a neighbor 4'' to 8''
the first day they were fine
but the next morning the Koi are all up on the surface air gasping
so we rigged up the pump to air spray [fountain]
but I find it hard to believe they sucked up all the O2 that fast
this is a 37' x 17' by 8' deep pool +30k gallons
any one else here have koi ?
