Hello. I have two tanks that I have bought off Craigslist, so I do not know what they are made of. Any ways to tell what they are made of would be appreciated. Thank you!
acrylic aquariums are basically plastic. usually doesn't have any of that black bracing or anything. the tank is one single piece.
glass tanks are made up of glass panes siliconed together. Usually has black or brown bracing around and across the top.
