okay just got a couple conchs and I also have a Halloween hermit. I bought extra shells for the hermit but hadn’t gotten them in yet. They fought and the conch spewed sticky yuck all ovreally the place. Is that normal? i had separated the two and the conch then FLEW across the sand at the crab! With the spewing....I separated them again, at which point the crab retreated to the safety of the rocks and I strategically placed some empty shells. Such drama!
