Damselfly Nymph Larvae Zygoptera

Found a few of these in our Axolotl tank tonight. They have appeared out of nowhere. What are they and should I be concerned?

(UPDATE) I did a bit of a google search (images) and I found a description of a Damselfly Larvae (Zygoptera species) and am certain that it is a match. Would love some confirmation.

Looks like a dragonfly nymph. Your axolotl will either eat them or they will leave once they grow wings.
