MTS out during the day?
Recently in the past couple of days, I've noticed that many of my MTS are climbing the glass during the day and are roaming around freely. Previously for the past couple of months, they hid so stealthily that I had to dig through the gravel to find them for my puffer at times when he looked hungry. My puffer passed two days ago and now there's no one to hunt the snails down, but it's hard for me to believe that the MTS are out and about just because my puffer isnt there to hunt them anymore. It's quite strange, but are there any other reasons MTS would be out during the day? I havent changed anything in my tank or added anything new.
