Causes, Dangers and Elimination of Damselfly & Dragonfly Nymphs - What is this Aquarium Pest?

Hi All,
Today I wanted to raise awareness for a very aggressive predatory pest that you may or may not find in your aquarium.
Damselfly and Dragonfly Nymphs can wreak havoc on nano tanks and shrimp aquariums, so it may pay to be aware of what this creature looks like and how to avoid them.

if you find a dragonfly larva, release it in a pond or lake near you! they help control the mosquito population and every mosquito larva helps

I just recently lost over $200 worth of neocaridina shrimp due to a couple of these in my tank that came from some dwarf water lettuce I ordered from Amazon. I stared at that tank hours a day and never saw them. I ended up emptying my tank and starting over because I thought something else was wrong, until I found them in the bucket I was draining water into. Disgusting terrible little monsters!

YES they are terrible and disgusting! Blech. My beautiful shrimp have been dying off too! Stupid me night water lettuce from some kid of craigslist. I didn't think much of it at first, even tho he had his tanks in his garage. He must not have lids on them and now I've found them in my large aquarium as well. They are black, sneaky and horrible! I just killed three today. How long will these things hatch for? I've had the floating plants for over six months! My shrimp are goners.

I have hundreds of them in a large old plant pot which I’ve been feeding with blood worm & daphnia but I didn’t notice the eggs in an old plastic tub. So upset cos they all died, I believe it got too hot in the plastic tub cos of heatwave. The adults were very big and skin coloured or yellow. Not sure what kind but their my wee sprites 🪰

I have been told that if you ever intend on keeping shrimp never ever use any medication with copper in it. Is this true because I was told it could become infused with the Aquarium silicone. What is your opinion Blake? Thank you for sharing your knowledge & experience.

Shrimp are definitely sensitive to copper but re: it getting into the silicone well many fish foods have trace elements of copper so i disagree with that

I can’t get a direct answer on google so hopefully someone here can help me out, I saw a brown damselfly nymph in my tank a few weeks ago but I was unable to catch it, it snuck out of the net when I got it snagged, today I caught a green one and I’m stupidly hoping that it’s the same one from before but it’s changed colour after moulting, if that’s even possible? I’ve stripped my tank almost bare and haven’t seen the original brown one since and after catching the green one today could I be lucky and it’s just the one? Or do they not change colour and I’m an idiot??

I was cleaning it out and once I drained the tank, cleaned it, put the new substrate in, than did several water changes. I than saw a little shrimp like thing right next to the glass so I trapped it in a cup and did research.
