Does this mean that you can cut off a tentacle and it will regrow, or does it have to pinch itself off? Also, i know that my anchor coral does not have sweeper / feeder tentacles, but why haven't i seen any out of my octo frog spawn? I thought that frog spawn normally have sweepers. I feed it and it like the light it is in, it has grown from 3 heads to 5 in about 2 months, but like i said i have never seen sweeper tentacles.
