Got 3 New Long Fin Serpae Tetras Today...

I wanted to add another black skirt to my tank but ended up getting these ones. They are so pretty! Anyone else have these?

Serpæ need to be kept in groups of 6 or more, and even then, are nippy little sods, miniature piranhas.

Careful it's a 50/50

Half kill your whole tank
Half are ok

OH my! I had no idea. Nothing I read about them said anything like that. I can add more. My tank is a bit full, though.
