This is worth checking out!! I used to catch some fairly big ones in our koi pond that would easily take out a full grown tiger barb.


:O

I've had my hands in and out of the tank all day, all plants removed and put back in; I'll be keeping a close eye!
 
How are they introduced into the aquarium?
 
I'm gonna starve my fish for 3/4 days, hopefully encourage them to seek out and destroy some of these nymphs, if there are more
 
That's a damselfly nymph, which should get 1.5" at the very most. They usually stay about an inch long.
The huge ones are dragonfly nymphs, which can get up to 3" long. They're a lot fatter than that guy, so you don't have a dragonfly.

1.5 is still insane to me, I'm going to keep a very close eye on the tank for anymore; do you reckon my blood parrot would eat them? She's around 4-5 inches and a fat grubber
 
Your blood parrot will probably love them. They're basically little candy bars. If you poke around in the plants a bit and stir any remaining ones out, she'll gobble them up. Tiger barbs or danios will also rip them apart, in fact most fish should go after them if they get the chance.
That was probably the only one. They're highly cannibalistic, and in an aquarium with a limited supply of critters between copepod size and fish size, the biggest ones will happily eat all the smallest- plus, your fish have probably torn a few apart.
