New fish dying.

[raphael_m]

I've had my tank set up for a little over a week with 2 fish in it and all my pH, KH, nitrate, etc. levels are fine. I just got home with a cichlid and 2 giant danios (going to buy a few more tomorrow at a different store). Anyways, I acclimated the fish to my tank per usual and about 10 minutes in one of the danios is already swimming erratically, has a pale/white color as opposed to the other one, wriggling back and forth and turning on its back. It also has a few red spots on it (they don't appear to be open sores). I think he was diseased and the shock from the move finally pushed him over the edge. Any thoughts?

You said it's been set up for about a week, did you cycle it? If so, how and for how long? What are your ammonia and nitrite levels? Did you add a dechlorinator to your water? Also what is the water temperature in the tank?

For anybody to provide any feedback you will need to provide exact detailed information.

I have cycled it and I used Prime, Stability, Aqueon bio cleaner, and Melafix when I set it up and have used it since its been running with fish. Ammonia and nitrites are 0 ppm and temperature is about 81 degrees.

What size tank do you have? What exact make/model filter do you have? How exactly did you cycle it? What are your nitrate readings? Are you using liquid tests, or strips? If ammonia and nitrites are zero and you have nitrates, you may be on you way, but if all 3 are zero, you're not cycled. Have you tested your source water to see if it has any ammonia, nitrites, or nitrates?
