Wierd nymphs

[Mayanearth]

Lately I have been finding weird green nymphs in my 8G tank. I don't know if it is related, but there have also been mutilated guppy fry in the same tank. Thank you for reading.

They sound like Dragonfly nymph, very capable of catching and killing small fish. Have you added any plants lately?

 

[Mayanearth]

No new plants.

Odd, usually they are brought in via plants or something new. Something must have laid eggs directly in the tank, can you get a pic of the invaders?

They are sometimes in the gravel hiding. But I will be able to take a picture on Saturday I think.
