Being new to snail keeping, I have a question. Why do some of my olive Nerites......um....."ride" each other (no pun intented). Are they, as the kids say today, getting their swerve on :hihi: ?
Since the eggs don't hatch in freshwater, you won't get more to help with the work either. :icon_rollLike stated, it is either one of those two options (eating algae off the shell or mating). If mating, they'll likely stay in that position for quite some time, which is quite annoying since then you only have one Nerite doing the algae eating work instead of two.
