Hey whats up, i usually don't post here.. i mainly just browse these forums for more things to learn about saltwater tanks. Right now I just have 2 damsels and a peppermint shrimp with about 30 pounds of live rock in my 55 Gallon tank. But somethings bothering me.. I have quite a few of these long thin white/transparent tentacles throughout my tank in poking out through my live rock. I have no idea what it is, and i have been trying to look it up for the past few days. i give up googling, I know they aren't brittle stars because i found out i had 2 in my tank a month ago.
