Damselfly Nymphs

[Matthew Lee Newell]

does anybody no of ang GOOD way to get rid of these pests?
?
obviousley you cant search the tank for them, is a gravel vac my best bet?
or are there any chemicals you can buy for them??

they kill small fish and fry

They are inverts so I would imagine a copper solution would work well, but once dead it would cause an ammonia spike due to rotting. Why can't you just fish it out with a net?
