Thanks everyone. I've been keeping planted tanks for decades so not a noob. Gravel is the only "rock" I'll have. Otherwise just plants and assorted tetras, platies, catfish, and a big black angel, all relocated from the 75 and 40 I had to leave behind when we moved.
I approach very little with a zen attitude so I think I'll go for glass.
I'd have an acrylic tank scratched up in no time.
