Have you got any idea's what sort of background i could use for the back of my tank? At the minute my room is a pale green and it just looks so boring looking through the tank. I want to jazz it up a bit. I have got 6 glowlight tetra's and i know that a black background would show them off a treat but would it make the other fish (i.e Angel, guppies, gourami's, ruby shark) look dull?
