After yesterday shoping I had one supraised guest. Asked you and turn out that it was a Brittle starfish. Good. Today I bought Sebae Anemone on the huge rock. After close look at home, under rock I foud this <picture 1 some warm?> and 4 of thouse on the rock <pictures 2,3,4Aiptasia?, never have one in my 8 years reefing>

that's a common bristle worm. you should know that after 8 years of reef keeping. As for the aptasia, if you don't add them, you'll never get them.

Looks like a bristle worm

It kinda looks like a fire bristle worm because of it's reddish color but I may be wrong. Those are not reef safe
