Thanks for the info, that's interesting!
I've put another photo on this reply.
I do have another of him on the glass side on so you can see a flash of colour in the tail, if that would maybe help as well.
I do seem to get a bit of algae growing in my new tank, and he is much more active now than in the old one!
How many in a group would you say?
My tank is a Juwel Lido 120.
