Dead Fish - Why?

[Flash]

i would have let your tank cycle a little longer before adding fish just to be safe.... could have been bad water? temp??

I suspect it was too many fish to soon. A new 10 gallon tank just does not have enough capability to handle three fish all at once.

Next time add the fish one at a time, leaving at least 3 weeks between purchase of each fish.
