green inch worms?

[Authentic]

purchased a acan frag and have noticed what look like two green inchworms extended from the base during the day,i will try and get a pic but was wondering what they may be.the color is bright green with darker lines from base to tip

Any chance they could be the arms of mini brittle stars? I get them in my frags all the time. The lighting may make them appear green, perhaps.
