i have had my tank for about 8 mo now, had the black plastic background and liked it, seemed to make all my fish stand out color wlse, just didnt like the cheap look of it and how it would rustle in the breeze in the summer etc.. So i figure a painted one would be ok. Might maybe just paint one of the big tanks and leave the other bare with no background at all. cant decide, like you said , its permanant. I think i will try the metallic highlighte background when i replace my 30 and 10 gallon tanks. I noticed the red empress really looked even more metallic and darker colors with it. Maybe i can keep a colorful male peacock in a 30 gallon. Or a dwarf species. Oh, i know, when i get remempress fry i can put them in there to grow out.
