Will the dragon fly larva kill my fish/shrimp or eat plants? Link to comment Share on other sites More sharing options...
Guppysnail Posted May 14, 2022 Share Posted May 14, 2022 (edited) It is a voracious predator. Small Shrimp and snails are preferred but if it is hungry it will eat any fry.  do you have damselfly where you live. They look remarkably similar behave the same. Edited May 14, 2022 by Guppysnail 1 Link to comment Share on other sites More sharing options...

I was also kinda scared putting my hands in the tank after seeing that! Link to comment Share on other sites More sharing options...

Depending on the species is how many eggs per stem they lay 6-20-50 -????  Try and identify the species. They burrow into substrate. A thorough vacuum will remove many. Shine a flashlight in at dark. The eyes will shine bright. I have no idea why my reply did not show here it is again  Dependingon the species is how many eggs per stem they lay 6-20-50 -????  Try and identify the species.

I took it out and killed it. Did it have only one tail, as it appears in the picture? Or 3 tails, as shown in the links? If you enlarge this image, you can see a damselfly nymph in the upper middle. It is lighter colored than the background. Unless you find a damselfly nymph in a newly started shrimp colony, or a very expensive breeding program, the small number of losses in livestock are far outweighed by the positive impact on the environment of keeping mosquitoes and other insects under control. I allow all the damselfly nymphs I find in my tanks to live, if they can escape predation by my fish. I am rewarded 3 months later with the best garden maintenance crew, that keep a wide variety of insect pests out of my orchids and food crops that I grow indoors. Damselfly larvae get a really bad rap in the aquarium industry, because people focus on one aspect of development (the nymph) and ignore the larvae stage (an important food source for fish getting ready to breed) And the adult stage that is greatly beneficial to humans and food crops. Just something to think about.  If your little aquatic guest only had a single tail, it was a dragonfly nymph. Again, they can be a threat to a smaller shrimp colony and a really expensive breeding project that is small. Outdoor tubs host entire egg casings of nymphs (both damselfly and dragonfly) yet manage to outproduce indoor aquariums without us humans removing the nymphs.    3 Link to comment Share on other sites More sharing options...
Jacob Hill-Legion Aquatics Posted May 14, 2022 Author Share Posted May 14, 2022 It had 3 tails so I think it’s a damselfly larvae and do you know how to kill them and get them out of my tank if there is more? Link to comment Share on other sites More sharing options...

Manual removal. They are tough. Anything that will kill them will indeed kill everything in your tank. 2 1 Link to comment Share on other sites More sharing options...

Remove them if you see them, and try putting them in an outside water container to complete their life cycle. 2 Link to comment Share on other sites More sharing options...
