Hi all, just traded some corals with someone and he gave me this zoanthids as a gift. However, I’m not really sure what kind of pink zoanthids these are. Are they just “pink zoa’s” or do they have a more specific name? Can’t really find it on the webs. Thanks! (Scopas for size )

A few pieces that i'm having a hard time ID'ing and was wondering if anyone else has a clue?

Sooo I haven't been able to conclusively figure out what this is, answers have varied widely. What are these things? Hasn't harmed anything yet and I thought it was just a type of algae, but last night I saw a worm poking out of the rock near it. It seemed to be searching for something, poking...

Hello, I've been battling this algae for a couple months now and I can't get rid of it... I can really use some help, quitting this awesome hobby has crossed my mind.. It's a very slimy fuzzy looking brown algae/bacteria. I've tried sucking it of, which reduces it a lot but only the top layer...
