They're very hardy and like to eat. Generally, I treat them similar to mini/maxi carpets without the lighting needs: feed with mysis/cyclopeeze or similar, and be careful with them around small fish because they will happily eat them if given the opportunity. Mine were kept in a temperate tank (55*), but all the suppliers I got them from kept them in tropical tanks, so they're nearly bulletproof. They prefer staying on rocks and readily walk around to find a good spot. I'm not certain on stinging corals and other anemones because they couldn't compete with the Corynactis in my tank in terms of stinging ability, but I would definitely expect them to pack a punch.
