Fuzzy dwarf would be the only fish you could have in that tank...
But if you don't do the fuzzy dwarf then do a pair of clowns and some other things besides damsels....
With the dwarf lionfish you could only have 1 fish without the lionfish you can have 5-6 fish in a 30 gallon if you pick the right combo...and if you keep up wkly water changes....
