Recently got another pint of blackworms to feed our ray (although he's pouncing bloodworms like crazy) and found a few of these buggers in there. What are they? At first I thought more fish lice, but then they stretched out like a leech. 

I'm at a loss, and they look sinister so it's bloodworms until I get some confirmation on safety.
