They are dwarf ceriths though, they are smaller than the larger florida ceriths we sell, so keep that in mind. They are great for tanks though. There smaller size lets them clean every nook and cranny, which keeps the algae, diatoms or cyano from spreading. We even send out extras. Because of their versatility and their size, (won't move even unstable rock structures), they are the staple of all of our cleanup crew packages. |
