Review on BiOrb 46124 0 Stackable Ornament Aquariums by Mark Scoggins

This is a very beautiful stone though; I didn't realize when I bought it that it was for a Big Biorb tank and not a 4 gallon tank. But since I bought it from stock and it broke, it was fine because it broke enough to fit a 4 gallon bottle. Tank! If it wasn't broken it wouldn't fit because it has to go through a round hole in the biorb filter tube. My fish love it! This is a really beautiful stone that adds great depth and volume to the aquarium.
