Sorry Paul.
I didn't mean to "scratch"
acrylic off the list of choices but after hanging around this forum for seven years I tend to get a lot of input and, based on that, plastic tanks are not my top choice. I do know that the technology has improved. More scratch resistant acrylics are now used than those of the past and many people do enjoy them.
Next month I deal with lighting and you don't even want to know what my opinion is on PC's.
