In the past I've accidentally introduced dragonfly nymphs in my tanks with disasterous results...now I see a new thingie and I'm wondering if it to will grow into something I don't want around...

I'm thinking a laval stage of something, but what..and what is it feeding on in my daphnia tubs...daphnia perhaps?
Anyway anyone have a clue what this is:

It looks like a damselfly nymph. Similar to a dragonfly larvae, but smaller and more delicate.

It's still dangerous to small fish.

So basically the things are feasting on my daphnia till they get big? We'll see about that
here is a page showing the two side by side...

Still, the pic I have doesn't match exactly, but damelfly larvae does seem to be the closest match

I only said it looks like a nymph. Could be something else. Might not even be from this planet. Could just keep growing and growing until one night it smashes through a window frame and eats you in your bed.

Damsels and Dragonfly larva have an extra set of jaws hanging down below the regular ones that shot out and grab their prey, like those crazy aliens that Segornie Weaver used to hang out with. You know, before she moved in with those giant smurfs.

...another planet is a possibility.... :thinking:

...See what I mean :confused: (but yup it does, <I know the EXACT scene> only not as fat or slimey)

...then why is it all I remember is that white T-Shirt she was wearing? Further proof silicone and D-cups are somewhat over-rated (I said "somewhat") :snicker:


How big is it
About .75 inch...not big really....but I've obviously not noticed nymphs before, so I suppose anything/everything starts out small...
I got some rare/pricey wild swordtals & killifish and would keel over if any of the fry got eaten,,,, :mad2: pissed wold be an understatement
