my koi aren't eating
they have always been like sport fish hitting their food. last week i put a water clarifyer in and found them at the top gasping for breath with one rolling. pond 1200 gal. i immediately bailed about 3 -400 gallons and splashed fresh water in it with salt and stresscoat. then i bailed 3 - 400 gallons again added stresscoat and salt and splashed the water in the pond to aerate. i noticed some shredding on the fins of the butterflys and added melafix. they seemed fine after that.
i had to go to the coast to board up for irene and the sitter i left with mother has a tasmanian devil boy, i told her he could not stay i wonder if he terrorized the fish. wound up firing her for other reasons.
water temp 79 - 84. no ammonia, nitrates, nitrites, ph good. i can't figure out why they're not eating.
