Concerning frozen shrimp & squid for my Eel. Can I thaw and re-freeze pieces of squid or shrimp and thaw again to feed my Eel? What I'm getting at is my bait shop sells a box of frozen squid. My Eel can't eat an entire squid (prob take ten feedings) so can I freeze the leftovers for another feeding? OR should I thaw once, cut up portions for daily feeding and put in separate baggies and only worry about it being thawed out once?
