bloodfin tetra, is this normal?

[maxima423]

lots of fin nipping!!!! they are harassing the cories as well, i havent seen them harass the BN pleco yet, so is this normal or should i be worried?

its normal. MOST tetras are nippers.

 

[maxima423]

oh are they =[ dang okay

 

[WhiteDevil]

Yeah thats the bad part about them. We got about 15 or so maybe less in the 210 and even with those numbers plus the 20+neons and cardinals then all the bigger fish they still beat the snot out of each other with no hesitation to draw blood.

My bloodfins are nippy but ony with my other tetras. They havent bothered my cories or BN yet.
