Why can't I keep fish alive...

[jgoldsney]

I have had the worst luck lately with keeping fish alive.....I am taking more care now than I ever have to acclimatize the fish but frankly I had better luck when I followed the not so good advice of a former LFS that reccomended just dumping the fish in the tank.

All my parameters seem to be normal but fish seem to be fine one day and gone the next.

Any thoughts on what could be causing this?

I am honnestly thinking of saying to heck with it and getting a tank full of bright blue damsels, they are cheap, they look good and they are tough.
