Anyone else see these in their tank?

Just watch. Six legs are fine, Seven or more are not...

Yeah, looking around, every article I can find regardless of their opinion either states they have seven legs, doesn't mention it explicitly at all, or the picture shows seven legs. The pictures of those found above, and my own, all have six legs. May possibly be completely different.

Its strange, I haven't added anything to my tank in well over a year (well, you know besides water, kalk and food) and I just noticed some of these Asterina stars last week. I've only seen a dozen tops, and then if I look while the lights are off or just after they come on in the morning. Typically see them on the live rock, not on any corals since I've first seen them last week. Mine are anywhere between 5-7 legs, primarily white in color with a dab of purple/red in the center of their body.
