Koi & goldfish acting differently
"John M. Darnielle" wrote in message .. . Hi! First, congrats if you are a ponder who hasn't been driven away from this group by the late unpleasantness. Second, my Koi and goldfish, about 12 in a 450 gallon pond, average length 6 ", have recently been spending most of their time at the surface under the fountain, They've pretty much stopped eating the tetra food sticks and prefer to graze on the azolla that has grown on about 1/4 of the surface. I've checked the chemistry, no ammonia, nitrates, salt at .05, ph at 7.4. The fountain seems to put plenty of air into the pond. Temp is at 64. I grew concerned when one fish died. Any ideas would be appreciated. -- John M. Darnielle Remove obvious phrase from address to e-mail me Turns out that the problem rapidly worsened, to include foul smelling cloudy water and another dead fish. I drained the pond and discovered a dead bird on the bottom. The fish were probably fleeing hydrogen sulfide, emmitted from the birds carcass, and finding partial relief in the filter exhaust coming from the fountain. All is well. Thanks for the advice i recieved. John |
