Hi! This looks like a great forum. I am interested in your thoughts on the mirror back tanks. My neighbor has offered me her 40 gal. mirror back as she's now using a 75 gal tank. I used to admire one in a local pet store but noticed the fish always had ick problems in that tank only. Is it possible that having a mirror back causes too much stress for the fish from background activity? Thanks for any suggestions, comments you can lend.
