Something is nipping my tetra

[raindream]

I am new to keeping fish and have 5 tetras, and two albino cory's, one of my tetras has had a bite (guessing) taken from his tail.....any ideas on who is biting??

probobly another tetra, cant see corys nipping at tetra's.

Maybe its a sharp object in your tank that hit has got caught on?
