Insect in my tank

Subject: Insect in my tank
by Fizz on 27/10/2009 17:19:02

I've just fed my fish and have spotted an insect in my tank sitting on top of some Salvinia. It's definitely alive as it moved but I have no idea what it is, and whether I should remove it or just leave it be?

It's about 2cm long with a very thin body, wings, and bug eyes on either side of its head.

Any advice would be appreciated.
