firstly, build a cave so it can hide and feel safe
then try what the shop was feeding it on and drop the food down into the cave - they tend to feed off the floor !
try also fresh mussel in the shell from the fishmonger
there is also an angel/butterfly mix which includes sponge...
Recently purchased - 10 days ago - Red Sea Regal Angel now refuses to feed. Was feeding in shop - brine shrimp / mysis. Would only eat fresh mussel first few days at home but now is not interested in live brine shrimp, mysis, shrimp, krill, cockle in shell or fresh mussel.
100 gall fish only...
