Indermark,
I love hawkfish
I dont have an invert friendly tank, IMO a hawkfish is way better and way more entertaining than any shrimp, so I figure, if the hawks eat the shrimp, so be it
disclaimer : Ive never had a $40 scarlet shrimp or anything like that, so if you do then of course you have more reason to be hesitant about a hawk than I am
