A Dwarf Lionfish (Dendrochirus Zebra, or Dendrochirus Brachypterus) IMO would be fine in a 55g. If you get it small, it is hard to get them to begin feeding, so feed it live feeder shrimp or feeder fish. He might even eat your damsels, depending on how big they are compared to the Lionfish.

LOL. Well, my setup is 75g, with a Scopas Tang, Blue Tang, Yellow Damselfish, and Snowflake Eel. Parameters are prestine. It's FOWLR but I will be switching over to reef, just because I want more movement, without more fish.
Thanks,
Chad
Not sure. I want to keep it and make it a reef tank, but who knows, I might sell it for the extra money to build the pond.
Thanks for the compliments everyone!
Just so everybody knows, the two tangs WILL be transferred to the pond.
