hello everyone, i am fairly new to this forum. i bought a 7" lionfish last may from a local fish store. they had feed him goldfish for a few years. i have been able to feed him frozen silversides since i got him. he seems to be around 8" now. i do feed him one per day. i am no expert on this species and i bought him because he was in a small tank and i felt bad for him. am i feeding him correctly ? thanks for any input.
