[Naughts]

Yes, they will need to re-establish a hierarchy due to the newcomers.

 

[Byron]

Yes, nothing to worry about.

Yes, though I would lower the numbers a tad under the circumstances. Cories are the most crucial here, I would get them up to 9 or 10, same or mixed species (but not the pygmy, keep the medium-sized species). And cardinals up to 10.

 

[Mathew1991]

Upped the Corey’s to 10 and the cardinals to 11

I still think the bh tetras are being aggressive and chasing each other around

Of course they are, that is their inherent nature. You see this in most if not all species lumped together in the polyphyletic genus Hyphessobrycon, some species more than others. But the decent number means it will be confined within the group, and as it is their normal interactive behaviour should not lead to anything.
