So I have now mostly established my 19L tank at work, and put an ornament in (though it really does seem quite large now that it's in there..). I also found an old webcam on my desk at work that was missing its download cable, so smashed it open and wired a new cord onto the circuit, imagine my surprise when everything still worked! I found some software that will update the page whenever movement is detected by the cam, though this does lead to a lot of 'oh there goes his tail as he leaves the frame' pictures.
Click to maybe see Edgar the plec!
The camera is pointing at the bottom of the filter as thats where he likes to hide, I will update this thread with some higher res pictures of the rest of the tank later on.
