Reply With QuoteI tore down my whole tank getting rid of it.. Best to get rid of all your moss and driftwood you have in your tank.. Bound to be more in your tank if you found one.
To my horror, found a molted skin dragonfly nymph in my shrimp tank!
I have been sitting in front of the tank but did not spot it, my tank is heavily planted...
Any bros can advise how to lure / find it and remove from the tank? I can't imagine it is happily feasting on my shrimplets now.

Mad about shrimps!

When I saw a damselfly nymph in my tank, I tore it down completely. Found a total of 3 in the end. My advise would be to tear everything down if your shrimp are expensive.

Where did you guys have your tank?Originally Posted by Emokidz
Beside the window???
Kind of shocking to have a dragonfly or damselfly flying into your house to lay eggs in your shrimp tank.
oh my... so I am not the only unlucky guy.
Was wondering why my shrimps keep disappearing, seems like tearing the tank down is the only way..
Better tear down, search and throughly remove asap!!!
They are having buffet in your tank now....
where did you placed your tank? is it by an open window or something? my tank is currently 'beside the window' but its always closed... i have dragonfly nymph issues with my koi pond but guess they have difficulty touching my koi anyway...

Dragonflies/Damselflies lay their eggs on driftwood/moss/plants at the farms and these are sold to us in the LFS. If you dont quaruntine stuff before adding them into your tank, the dragonfly eggs will hatch successfully in your tank. Kind of like a trojan horse.

Argh... I came close to tearing down my whole tank but found nothing... still don't feel at ease now...
Any other ways to try catching it? By trap?
Anyway I doubt the dragonfly / damselfly came and lay her eggs in my tank.
- my tank is quite far from the window
- I am staying at the 11th storey, don't think they will fly so high up just to look for a breeding puddle.
I want to know how many times the dragonfly nymph will molt before the dragonfly comes out?
Oh Not, from Wikipedia,
The larval stage of large dragonflies may last as long as five years. In smaller species, this stage may last between two months and three years. When the larva is ready to metamorphose into an adult, it climbs up a reed or other emergent plant. Exposure to air causes the larva to begin breathing. The skin splits at a weak spot behind the head and the adult dragonfly crawls out of its old larval skin, pumps up its wings, and flies off to feed on midges and flies. In flight the adult dragonfly can propel itself in six directions; upward, downward, forward, back, and side to side.[7] The adult stage of larger species of dragonfly can last as long as five or six months.
In this case really tear down and hunt down that nymph.
In my experience dosing the water with a colored medication helps bring the larvae out as well as make them easier to see. Right now you are looking for a semi-translucent creature in water which is pretty tough. I usually pick a medication that won't harm my fauna (something like Myxazin from Waterlife which turns the water green) and then dose the tank to help create contrast. I managed to kill 2-3 of them like that. Good luck.
Thanks wolfgang for the tip. I will continue to monitor my shrimp count first, I don't really like medications in my tank.
Anyway, I will have to correct on what I said in post #9, I just saw a dragonfly flying outside my window (11 storey)... arghh...
- they really fly quite high
but I am very doubtful that they will fly into my living room just to lay eggs....
oh yah, thanks ckckjn
I found the molted skin near the wateredge at one of my drift protruding out of the water. Hopefully it was the last molt..
