Hello Folks, I'm new to the forum and am enjoying the breadth of knowledge shared on this site. I see this question was posed once in Nov. but couldn't get a clear read on the responses. A friend in the glass business tells me I'll regret buying acryllic. I was leaning toward a Tenecor flat back hexagon 85 gal. Will scratches cause me to wish I went glass?? (I read they can be buffed out??). Also, what type of gravel am I looking for. I was going to stock semi-aggressive fish instead of cichlid's.
