White tubes on rock

[PotatoPig]

I have some rock in QT and two pieces have a number of tubes on them. These are narrow, and I haven’t seen anything going in or out of them. Good, bad, neutral?

Possibly vermetid snails? Don't think they're feather dusters.

The meandering shape of some of the tubes makes me think feather dusters.

The white ones are small featherdusters.

There are a few tiny featherdusters that pop up elsewhere on the rocks.

Another question - I don’t really have a photo because they’re so tiny but there are also a BUNCH of minuscule snails scooting around on the rock that look a lot like your regular land snails with rounded shells, just very tiny (1mm ish) and under water, obviously. Is there any good way to figure out what they are before they grow or safeish to assume these are good guys?

Gonna keep an eye on them for a bit.

Looks exactly like my featherduster tubes

See if you can spot any featherduaters poking out of any of them. They could just be tube remnants as well.

Looks like tiny dusters are starting to venture out of one of them now.

Yup that's a duster. I bet if you feed one of the powered coral foods it will come out

A bumper crop of feather dusters!
