I would be happy. Xenia and star polyps grow like weeds. I do not think your chalice is a named chalice. It looks healthy and has lots of eyes. I can not tell you what family of chalices it is. There are so many and many look alike when they are small. But the care would be the same as all chalices.
Great one. Many find a named chalice there's looks like and wrongly slap that name on it. Which is not right but does no real harm until you sell it to someone under the erroneous name at the higher price.
