Hi all,

I found this bug in my tank tonight. It was inside them stem of some Elodea.
I was watching the tank carefully, looking for signs of pearling (which I
have woohoo!), and I noticed the shadow twitching.
It is a few mm long, yellow with a green line down it. The picture doesn't
show tufts of hairs along its length.
Anyone know what it is???
