I think most fish if healthy would be fine.Such a cool creature. I want one badly, but I’ve just always been worried about my beloved tiny wrasses around these.
Do you have mostly larger fish? Or do you keep small ones as well?
My smaller fish are a mandarin, sunburst anthias and a pair of bangaii.
However I introduced sexy shrimp and a porcelain crab before and they tried to host the nems and got eaten . Got a stars and stripes shrimp living on the green nem though.
I feed mine once a week a piece of clam to keep them happy.
