Well, I think it is starfish! It doesn't have suctions on the tentacles, but it does have many legs. We saw it living in a tank at our local rare and tropical pets shop. It is a neat store and have so many things that I don't see at regular pet shop.
I went to this store twice, and I believe they were out of business soon after! I don't think with such rare and specific pet shop like this one could stay viable here in our small city! There are many collectors or people who would be interested in keeping a starfish or octopus if it is!
