I don't have any SW equipment....I only keep FW fish

I think they're find unless they start to fight each other you'll have to give one up.

The fish should be fine in a few days. Post some pics

Watch them for any diseases, injuries, etc.

How long have your tank been set up? Possibility is that they're still stressed out from moving. Do you have lots of hiding places? They will feel better if a few hiding places is provided.

What's your nitrates levels? just want to know. really high nitrates can affect the health of fish.

If your water parameters is fine they should be ok though, just wait a few days and keep observing them.

Damsel:
it depends. Tank size, rocks, whether the fish had disease, acclimation, injuries, store water parameters etc.

What's your water parameters?
Send me a PM with more info. I can't PM you for some reason.
