Hey, don't feel too bad - it's just frustrating when folks see posts like this. But, it's NOT your fault. You can do whatever you want, BUT, here's what I would do:
Take your livestock back. ALL of it. That way, no one can accuse you of killing anything!
Then give us details on your tank, and how much rock, live or dead, you have in it.
Just plan on this: you will need to wait 6 weeks before adding real livestock. BTW, you will eventually hate your damsels - they are mean. So, I'd suggest you NOT replace them, that way you won't have to find a home for them later.
