Guppie Acting Really Strange

[migdem]

I have a guppie that i got it about 2 days ago and 1st day was ok but now she does not want to eat and no activity at all. I saw that someone from my tank nipped her tail and thought to put her in the breeder so that no one will try to nip her. I still left her in the main tank though. What could be the problem. I do not think that she is due because her belly is not so big. Also she is always on the top of the tank.

Any help please?

i am guessing you have a newly set up tank, did you cycle it at all, do you have a test kit?
