Is it okay to use flat marbles at the bottom of my 1 gallon Betta tank? Some people suggest gravel, others say sand, and some say marbles are the best. He also has a soft plastic plant, is it possible he is scratching his fins on it?
Yeah, that's the PETCO 6.6 gallon bookshelf tank. It's about $50 but it comes with a filter, a light, the cave, and even some plastic plants that I didn't use.
