What tank 'backgrounds' do forum users recommend?; to hide the wall and the heater/filter wires etc - and to best 'push' the contents of the tank forward). I was thinking of just a plain black background - or blowing up an underwater image (I found a nice one of underwater mangrove roots etc); then abstract/fuzz it in something like photoshop to give a 'feel'... rather than the hideous, tacky backgrounds (flat and 3D) that are widely available (don't mean to offend anyone - they're just not my taste!). Thanks
