First of all my apologies if you have already read this! It is a bit of an over-lap with a post I made in the beginners section, but it didn't receive much of a response there, so I thought I'd ask here too...
I have observed some interesting behaviour with my Gold Tetra (Hemigrammus rodwayi). I currently have five of them in my 130L tank. Two of which will rise into the water column from the vegetation, and appear to mirror each other - holding their bodies at a 45 degree angle to one another, one below and slightly to the side of the other, whilst simultaneously shaking their tails.
A little bit like this, when viewed head-on:
They then move up and down the tank doing this...
Does anybody know what this behaviour is?
