Damselfly Nymph

[Jer-]

Hi

I just found and netted a Damselfly Nymph in my planted tank.
Should I expect more? and what can i do to stop them from growing in my tank?

I have read that they are predatory of small fish. Cardinals and Amano shrimps in that catagory?

Thanks in advance

I no they do eat small fish but if you have got it out hopefully they will be no more.
forgot to mention that they frequently come in as eggs (or very tiny nymphs) on live plants, and grow up in your tank until they are big enough for you to notice them. Do you have any live plants in the tank?
