Re: Pond fish mysteriously dieing
#3
thanks for the response.....water fall is off, there is no evidence of infections, red vein or any evidence the fish are dead untill they are floating. Their scales are all normal, and there is an 8 inch air stone in the pond, there is the return from the filters going into the pond, the only still part of the pond is at one side where the liily pads are.....depth of pond is 2.5 ft deep not 8ft as above...lol.
Its a difficult one as they all feed well, spawning, splashing, surfacing ....just a bit stuck now and know im out of ideas.
