Sounds like you have four species of tetra, two of each kind?
 
If so, that is your problem. Social fish including most tetras can become very anti-social and aggressive when not kept in sufficient numbers of their on kind.
 
Six per social species is often talked about as being a minimum social group, but I've found 10+ shows a marked difference of 6s.
 
What species have you got in there?

As N0body says Tetras prefer to be in groups of 6+.
I have a 5ft tank, 260ltr with tetras
Neons, Penguins, Glowlights & a few Platys and Corys.
Tetras are all in groups of 12 and they get on well together.
I would add a few more to bring the numbers up. That should cure your problem and stop the one being bullied.
