    HELP! What is this…a ?

    So I’m new at this salt water thing and this is my first hammer. I noticed this “pineapple” shaped growth forming on the skeleton of my gold hammer. Anyone have any idea what this is or what it could be? Any input welcome. Thanks for helping a novice out (in advance)!

    Is this vermetid snail or… what? (I’m new)

    Hello! I’m pretty new in the hobby! Today I just noticed this kind of red worm on my euphyllia glabrescens… Is it vermetid snail? If not what could it be, the bottom seems attached to the body of the coral. Thanks for your time!

    Mysterious Crab

    I’ve had my tank set up for over a year, and never had added any crabs. My tank is a mostly fish only tank, with 2 anemones and some GSP. So I was caught by surprise one night when I spotted a mysterious crab on the rocks. My theory is that maybe when I was adding pods to the tank, there might...
