Its tentacles around the green part look triangular , sharp and pointy .

Wow ! Thank you tht79 ! Much appreciate your help to id .

I went to read up on "walking dendros" and read that they actually move around ! Strange because i have kept mine for about a month and it never moves . Got it foc from a generous reefer who used super glue to stick it to his lr . There is still hardened glue on the base of the coral . Could this be the reason?

Ohoh im sorry . A worm is needed for transportation , it rides on the back of a worm , thus able to move around.
