Seems to do some growing. Not sure on this one.
It has a yellow tentacle which moves around near the top. I've seen it drag in some dead matter via some sort of clear mesh. It just appeared one day, hasn't moved or grown for a month.
Sorry about the medicore picture quality. Clarity goes down a lot when your glass isn't clean
