ok so i was doing some cleaning on my tank today and i accidently hit the bubble i posted a picture up of on here and kinda said oh s@#t (someone posted a comment saying that poping it would be bad) so i kept an eye on it and sure enough a couple minutes later i had a baby bristle star appearing from undernieth my coral ISNT THAT CRAZY! i have a big brisle in my tank but only one its probably about 8-10" round i would guess ( thought id share because i think its pretty cool) if i can get some pics il post them.
