Ive been trying to get a pic for a while. Its really hard to forums the camera properly.
I tried an under water camera which scared him into hiding, unsurprisingly.
The price i thing was about £4.
I got a weather loach and him for £9.** (not sure the exact price.)
So it must be around £4.
Thanks for the above link, it gave me an idea.
The topside looks like the picture 3rd in from the left.
Ill attach a picture i took, its not great but might give you an idea.
Terrible i know, but it might give you an idea of colour...
This is his belly, does this shed any light?
If both are useless ill try to get him on the back of the tank, or even in a bag to photograph.
