Strange insect creature?

[jpoko]

I found this in my 29g freshwater. Any thoughts? It's about one inch long.

Looks like a damsel fly nymph. Hope you don't have small fish, they will try catching and eating them.

Von rio tetras are the smallest- not a problem, I hope?

I'll do some research.

Thanks so much!

Definately a damsal fly nymph. Predators; I would get it out of there.

So is it possible that this damselfly nymph matured and then left the aquarium? I found a really odd and very similar creature on my window sill!!! I have searched and searched the aquarium and I can't find it anywhere.
Thank you for your help

Yes. Damselflies lay their eggs in water. They hatch and the nymph stays in the water for months Then they emerge as damseflies. i have no idea how it got into your aquarium, but they are voraceous predators. Make sure it is out of there.
