I received these with a tank a purchased awhile ago. I am never going to use them, not even sure why they are still here. There is green and clear rocks of many shapes and sizes. If anyone wants them, they are welcome to them. Pick up is preferred. There is quite alot and they are pretty heavy. Not sure how many gallons the bowl is, but it's like 10"x10". And u can have that too. If anyone is interested, please let me know befor they end up in the trash.. thanks
