Black Widow Tetras Acting Different In Bigger Tank

[Durbkat]

As some of you may know I cloned my 55g yesterday and added all my fish from my 20g to the 55g and today I noticed that the tetras seemed to be rubbing against each other alot so far none of the fish has no fin or body damage are they just playing around, setting up a heirchery to see who's boss, or are they bullying each other?

Might be the water is new, watch out for itch.

Could be something like chiclid behaviour, there reestablishing territories and the pecking order, if you have a test kit just check the water for ammonia and nitrite to be sure.

It could be the water or maybe a disease but i doubt it
I have tetras and have had for i think about 6 years and they do this all the time. They just rub against each other and then run away. I dont think this is bullying, just playing around. But it is always good to check

All right thanks guys....sorry for taking so long to write back because with I'm at we just had a tornado and I was in the basement and there were reports of funnel clouds about a mile a way. I was really freaking out. Also as I was yelling at my neighbors to get into the basement I heard that train whistle noise the tornados make when they are on the ground which meant that it was close to where I was.
