well i have a 180 gal and a 100 gal tank thats running and it has no background right now. i cant paint it cuz my dad said no. so im prolly goin to get a big cardboard and paint that then tape it. but i was just wondering. whast the best background. i know a lot of ppl use black but then it just seems too boring. does anybody still use those fish backgrounds? or is there anything better?
