Good afternoon I found this behind my live rock I purchased recently can you guys tell me what it is and if it's cool to leave it? It looks pretty cool thanks in advance (warning camera phone photo) [emoji41]

Clove polyp. Cool hitchhiker, but like the green star polyps can take over a tank. Keep an eye on them
