Quick question.

K7BMG · Mar 24, 2020

Sorry I am heading out of town for a few days and don't have time to search myself.
Are these bad?
I also think maybe I have vermited snails, as I found small hard brown tubes sticking out here and there.
This is under a mushroom.
There are two in the picture, but I have not seen anything protruding out of the tubes so far.
Was cleaning things up for a future transfer and did a H2O2 dip to rid the unwanted algae, and came across these.
Mushrooms doing fine and looks like the algae is gone now.
Thanks for all responses.

The brown tubes are more than likely vermatid snails. Pull the rock if possible and crush them...or attempt to crush them in the tank.

Other than that, I can't really make out what else is in question by looking at the small pic while on my phone. Hopefully others will be able to see the pic more clearly.

I confused the situation as I took pictures of the white tubes.
I have both white and brown tubes,
There are no brown tubes in this picture.

Both are hard and assume calcium based.
The brown ones are half the diameter of the white pictured and straight for the most part.

I dont know if the white tubed critters are bad guys or good guys.
The corals they are under are doing ok though. My gut says harmles good guys.
The white guys are under most everything not just the corals, but the rocks as well. They turn, curl, and are not straight.
Almost tube worm feather duster like. I have not seen anything comming out or moving. They are also under the rocks and corals in the shadows, not on illuminated surfaces.
