I've been wanting to add an underwater sandfall to one my aquariums. I love the way they look and I absolutely enjoy building things. I seen a video of someone building a terrarium and using some kind of black board or sheet to glue rocks to that gave the appearance the rocks were much biggerthan they were. It also had the entire filtration system built behind it so it was invisible which is highly appealing as well. Any ideas as to what I could use to make something verysimilar but safe for shrimp and nano fish. I want to make it the entire background of my project aquarium and have a wonderful azalea root that would be the perfect center piece to the entire pic. I just need help identifying materials that won't harm the livestock.
