    So what are these line things coming off the coral?

    I had tested out shooting some food at the coral using a turkey baster and noticed this shortly afterwards. I assume it's some sort of way for the coral to grab the food.

    Anyways here's a pic. Hard to see, but it's he wavy dark lines

  2. Can't really see the picture on my phone, but it sounds like you're describing sweeper tentacles. He's just checking to see what's in reach and whether to go to war. Hammers are pretty aggressive to other corals.

    Are there vermetid snails on the rock that the hammer is attached to or the coral skeleton itself? If so, and the stringy stuff is white/clear, it's probably vermetids throwing out their mucus web to catch food.

    If it's brown and coming out of the hammer's mouth, it may be poop or zooxanthellae being expelled, but poop and zooxanthellae don't usually come out right after feeding normally.

    Not likely a sweeper, think jorahx4 is referring to the stringy stuff. Sweeper would just look like a stretched out, thin and elongated tentacle.

    stringy clear/white stuff. the hammer is just on the frag i got it on, sitting in the sand. nearest coral is 3-4 inchs away. i only have 2 snails. neither were near by. and yeah bruce it is hard to see it in the picture haha. my phone is terrible at taking pictures.

    Vermetid snails don't look like snails. Google it.

    Hard to see in the pic but mostly likely either sweepers to catch food or mucous from the surface. Either way it’s fine.

    Do hammers have sweeper tentacles? I’ve never seen them on mine.
