fish Laying on bottom of pond...what does it mean??

:help: I am not sure what to do here...I have just put a new garden pond in. Its 125 gallons. I have done all the water checks and everything seems to be ok. I even took the water to a specalty store and all checked out well. We allowed our pond to establish itself for almost two weeks with all the plants and all.

Now the situation is we just put our fish in yesterday and they were fine but now they seem to be very lathergic and are laying on the bottom of the pond. there also seems to be a slight "fish" odor coming form the pond. I have again checked water and nothing seems out of place, what could cause my fishies to be like this??

Thanks for all the advice but it turns out that I had some sick fish. I was able to locate some pond owners in the neighborhood and talk with them. Apparently I did not buy my fish at the quality establishment that I beleived it to be. After the sick fish, which were coments, were removed form the pond everyone else brightened up and appear to be doing great. Even the plants seem to be greener....Note, I do have a water test kits as I stated and checked the water what seemed to be every 15 minutes. My pond is 125 gallons and there was 5 coments and there still is 3 (here goes nothing...I will spell it the way it sounds) sabumkins......Thanks again.....
