Damselfly larvae in shrimp tank

[AtHomeWithTwins]

So i was just checking out my rcs tank and noticed this horrible looking little bug. I thought at first it was a shrimplet, but upon further inspection it definitely was not. Did some "googling" and determined it was a damselfly larvae. Anyone else ever had them? Think theres only one or am i going to find more? Im not a fan of creepy crawlies so i hope he was a loner! Any thoughts?

I had one that came in on my plants. Haven't seen any more. It will definitely eat shrimplets and possible even adult shrimp as it gets bigger.

Yes, they will eat shrimp and baby fish. If you have large fish, they might make a snack out of it, but unlikely because they are very good at hiding in crevices. If I were you I would remove it.
