• Are small horseshoe crabs a good idea for a marine tank?
  
  They are good sand sifters. Make sure that the foundation of your liverock or coral is stable since they have been known to topple over some structures. If you have large predators like puffers or triggerfish, you will not be able to keep the horseshoe crabs.
