i've a bumblebee goby in my brackish tank. i'm feeding it a bloodworm every other day (when i feed my f8 puffer bloodworms). it seems the bloodworm is too big for it. after it swallows the bloodworm, it opens its mouth wide, and seems to try to spit it out (but sometimes never seem to). there was once i saw it spit out the (transparent) exoskeleton of the bloodworm after a few minutes. would this be alright?
