    They are indeed dragonfly nymph and they to me are one of the best predators in the world. You better do a detailed sweep of your tank with a pair of tweezers to get rid of them, else you will lose all your fauna. Get a netted cover for your tank too, to esnure that they will be no reoccurrence.

    the pic i posted is alittle deceiving... its actually much much much smaller than it is... say its probably 5mm long? so its impossible to do a sweep of my tank... i need to have super eyes! i still have no fishes in my tank... only cherries and yamato... how la how?

    cheers!

    try to take out the cherries, and put some betta or other predatory fishes, they'll be cleaned in a blink.

    In that case, I go with hwchoy idea. maybe a small puffer be good. But be sure your shrimps are gone, else the puffer will be a bigger headache.

    damselfly nymph guys... dragons are abut 3 cm and lack the tail. Of course ranma would be the expert on this.

    Having said that, these guys are equally dangerous to small, soft bodied animals like fish. But excellent food for bettas

    Dragonfly nymphs dont have to be 3cm.. but yes they lack the external GILLS.. those aren't tails.

    that would be what dragonflies feel like.. they have "internal" gills
    Being like a damselfly would be like having your bare lungs externally attached to your sacrum.

    Dont know how to help Flush.. you can try just manually removing them..flush them out.. pun intended.

    i guess the only way seems to be removing them manually.

    Well, at the current size, I don't think their are going to decimate the shrimp population quickly yet.

    Ranma, how many of these will a damselfly produce in my go? At least flush will have an idea of many to find.

    Flush, you just have to be really vigilent and keep looking for them daily, or overhaul your tank. You can't trap them as they are lots of other stuff to eat in the tank and they will not go for baits like fish food.

    Can you remove the plants in your tank? If you can, remove them and it'll be easier to look for these fellas in a bare tank. You'll need to look everywhere, under over-hanging rocks, driftwood, behind piping, internal filters etc. For the removed plants, rinse thoroughly and examine for nymphs. You can also place them in another tank with a common fighting betta or puffer and just starve the fish for a week.

    You can also try bleaching the tough plants in a 19:1 water:chlorine bleach solution for 3 mins. You'll need to rinse thoroughly and soak the plants in some water with a liberal dose of anti-chlorine before returning to the main tank.

    Or replace the plants you removed with new plants.

    Actually that depends on the species Vinz.. it ranges from hundreds to thousands.. but i doubt Flush got a batch of plants with hundrreds of egggs on it and didn't notice... They hatch between 5-40days.

    Wow... hundreds to thousands. Well, a majority would have become fish fodder. Those that survive would wreck vengence on some of those fishes.

    Well, the nymph could have hatched and hitched a ride in on a new plant.

    Anyway, Flush, did you get new plants recently? I found a dragonfly/damselfly nymph in my tank some months back, but I didn't get new plants then, so it could only have come from a dragonfly/damselfly laying eggs in my tank.

    thanks guys, appreciate all your help... no, i got my plants about 2 months ago... i noticed it because i was admiring the little shrimps that hatched less than a week ago... then saw this alien... i doubt that a dragonfly or a damselfly flew into my house... although there's a chance but it's slim...

    crap, hundreds to thousands? i was happy i caught 1... haha! i think the best solution is to remove my shrimps and throw in a few puffers or bettas...
