I posted yesterday in the pond section but nobody replied.......Does anybody know about caring for koi and water requirements? My neighbors moved about 2 months ago and left their koi behind. Its a very small pond. About 3 1/2 feet wide and 1 1/2 feet long maybe about 20 gal
with a pile of rocks in the middle. There are about 7 koi between 6 and 9 inches and a tiny baby! Of course they abused every animal they ever had, cat, dog, etc. Their turtle even ran away, seriously.
