So, I've just come across something weird today. So at the beginning of the day I see a cerith snail riding on top of another cerith snail. Just now, I saw it again...This time on the front glass just before I went to turn my room lights off for bed. Just wondering, are they fighting? My thoughts not likely. Are mating? Probably pretty likely. Are they just having fun? Maybe, maybe not, but it's fun to believe that they are! I just missed them because when I got the camera out they split up.
