i have a newly setup marine tank and i just recently put in a large live rock. on one side of the rock is a brown hairy sack thing that looks like a big hair ball however inside is a little critter of some discription! the hairball is about 10cm long and 5cm wide and the critter pokes out little tentical things and feelers every now and again but mostly all you can see is it's shadow. i just wanted to know if anyone out there could possibly tell me what it is and if it needs any thing? and can it come out??? i have asked the pet shop i bought it from, but they have no idea about saltwater fish at all. i would appreciate any input. thankyou
