it is possible its a snail, and pods
are not a eye sore they are a sign of a healthy tank. You want MANY pods
in you tank and different types of worms. All signs of a healthy tank.
Yes, fish will eat them but hopefully some will be left behind to populate. I enjoy looking at the pods
in my fuge as much as my fish some days... Who would have thought about all the little critters in a fish tank..
The stars are commone hitch hikers and when they loose a leg it most times turns into a new star. So you probably got a frag of a star and its turning into a full one. Some stars have 6 legs.
