12g. nano fowlr tank??? Fish??

 

I'm wondering if anyone has experience with green spot puffers, which I understand can be acclimated to fresh, brackish or salt water.  We are considering small puffers for our 12g. nano, and I'd love to see if anyone has more knowledge regarding these little guys.  I've also been looking at a Valentini puffer, but I'm not sure what fish would work with him in the tank.

 

Another fish for consideration is a dwarf lionfish of some type.

 

I'm not sure what will work in a the tank and what won't, so any first hand knowledge you can share will be appreciated!

 

Thanks.
