Danio Killed Guppy

[homerhotspur]

Further to my earlier post, I have to report that the Guppy was dead on the bottom a few hours later. It seemed that one particular Danio was harrassing it. This follows finding a dead Long finned Zebra Danio only yesterday. There must be a connection between these instances. The remaining long finned fish in the tank is one solitary Guppy who at the moment is being left alone. Any suggestions?

We are now down to 4 Zebra Danios, 6 Cardinals, 4 lined Barbs, 2 Corys and 1 Guppy.

I presume the Guppy just died from stress rather than a physical attack?
