Can anyone identify this weird bug that was coming from my puffer aquarium?

Looks like possibly a dragonfly or damselfly nymph? Someone else may know better, but the body shape looks like that to me. If it is, check for others and remove if you can. They're bad news if you have shrimp or very small fish.

Thanks for your reply. Luckily, this is a puffer aquarium, so all good. I do have several neocaridina and CPO aquariums as well, but they're in a diff location and pristine.
