Hi Frans does this apply 2 all species of lionfish coz I found my dwarf 2 be much more passive than his cousins in fact he was happy 2 chase around and gulp down even flakes and pellets flying around with the power heads on!
Nick as far as I know, the clowns should be ok, like Chika said, as long as the clown in quite a bit bigger than its mouth, cause its bigger than you think!
I just fed my small lions, the one is only about 20mm long, but ate a live shrinp about 25mm long!
