Hey. A couple of weeks ago i bought some guppies, and they bullied my Albino cory to death, kept nippng his fins and stuff? I was shocked cos i thought they wud get on.

Then i had a bit of a crisis with my tank with nitrates and stuff lost all my fish except 1 guppy and 1 neon tetra. And now he constantly picks on the neon tetra?

Why is this?

I thought guppies got on with most fish? :S

A picture of this guppy may help solve the case...
It could be that what you thought was a guppy may be something more aggressive like a panchax or something.
 
Hmmm :S I just looked that fish up on google and its not the one i have :S

Im sure mines a guppy :S Maybe its just a bit of an aggressive guppy. I always get the baduns out of the group Lol
 
I don't want to worry you, and this is only one possibility, but one of the symptoms of nematode infestation can involve behavioural change including nervousness and aggression - is the guppy sometimes unduly jumpy? Thin and/or bloated? Any stringy white poop?
This is actually a toxicity reaction, so it could also be associated with water quality or other disease issues, among other things.
But it certainly doesn't sound like typical guppy behaviour...
 
That attack does not sound like a guppy at all. Similar looking fish are gambusia affinis, called mosquito fish. If your guppy came from a feeder tank, it could actually be a gambusia. They show up quite often as feeders.
