Potters Angelfish
 

Is this fish reef safe? What is everyone's opinion?

As with almost all angels, its totally hit-or-miss.

Pygmy angels are a little less likely IMO (knock on wood)

Potters dont do well starting out in captivity. Many dont start eating for most owners. if you get one eating they are just as hardy as other small angels.

Just like other small angels its hit or miss on corals. I have one for a while now that has not nipped at any acro or clam. He is very healthy and eats anything I place in the tank. I got lucky with mine.
