I have two Mystery Snails. For a few days, they were mating constantly, them stopped (well, I didn't notice them mating). Now my Gold Mystery Snail is firmly attatched to the shell of my Black Mystery Snail. The Black has been on the go all morning long, while the Gold was active this morning but hasn't let go of the Black's she'll all day and hasn't really moved otherwise. Do anyone know what he might be doing? Is he trying to convince her to mate again? Should I try to remove him? I would add pictures but I'm not sure how to on my phone..
