Crickit;
I wouldn't try a Powder Blue in a 55, it just doesn't provide enough room for the fish. They are very active swimmers and difficult fish to keep, the combination of the two usually does not lead to a happy outcome
Good fish for a 55 fish only could include hawkfish, clownfish, dwarf angels,
fairy wrasses or wrasses under 6". All kinds of blennies and gobies to choose from; firefish, jawfish, cardinal fish...the list goes on. Check
Scott Michael's book, lots of good info and it's not very expensive.
HTH,
~Alice
