Ok, so dumb question I'm sure, but can MTS flip themselves over once they are upside down? I just got some and a few of them keep getting flipped over. I put them back and they crawl around, so they are not dead.
I've never had any of these issues with my mystery or nerite snails.
Yup, they can. I removed some rotala that has MTS on it from my tank and shook the MTS off. Some MTS landed on their backs. I check back 10 minutes later and the MTS are right side up and crawling away.
