Identification of zoa/polythoa

[rblackdvm]

These came attached to an order of radioactive dragon eye zoas. Since I've had them colonies of whammin' watermelon and Green Bay Packer zoas have also began growing. I can't figure out what this guy is. It was pretty brown when I got it, but it is starting to get more green as I feed it.

Those are invasive growers, I suggest keep them in sand bed or they'll take over your how main rock work. In the likes of texas trash protopaly's, grow like weeds
