LOL - True.
I'm not sure how much longer that background will last though. I only have a couple ramshorns in there, but they're making impressive progress on the hair algae!
I do have a black background on the tank as well - it's actually black shimmery material that I bought at Jo-Ann Fabrics. I sewed the edges so that it won't unravel, and then put that sticky-backed velcro on the back of the tank on the rim, and then matching velcro on the black material - I can take it off and throw it in the laundry when it's looking grimy, and put it back up with no problems.
Worked really well for me. I am probably going to utilize the same method for a background for the new 75 gal too. Just haven't had time to get to the fabric store yet. Gotta love clearance racks there! hehe
