hrmm yes, thnx for all the ideas guys

maybe i could put like a white towel or something on the back of the tank... pitty i dont have one! but maybe that'll do something.
I could try white gravel but thats lots of effort

and money.. and it'll probably go green pretty quick eh? Should get some little waterproof LEDS and make a lego wonderland under the sea

that'd be awesome!
But nuff dreamin i need some real goals...
