What is this?

[Aquagirl84]

Anyone know what that swirly sort of reddish brown thing is attached to base of frog spawn?

Its also on the live rock. It’s hard to the touch.

Possibly a vermetid snail?

you do not need to shut down your tank
over a vermetid…

try some bumblebee snails first…
they worked for me.

Why ?

No they’ve clearly been here for a while..literally covered over all the rocks and slowly killing everything. We have bumblebees too.

You can use a pair of needle nosed pliers, or dykes to crush the tubes and kill them.

i use bone cutters and make sure to get the base, as that's where the snail will retreat to. if you don't all of the tube, the snail can survive.

i also wouldn't shut down a tank due to them, but i would do my best to get them under control and they'll probably come back. they're hard to see and even with manual removal i think some eggs will likely survive unscathed.

i'm curious if anyone has tried to move infected rocks to a fallow holding tank in hopes of starving them to death while keeping the rocks live. i'm guessing that won't even work as anything fed to keep the bacteria going is also going to feed the vermetids.

unless you start with dry rock, replace every frag plug before you put a coral in your tank, inspect the coral itself and any invertebrates you put in there, i'm not sure its possible to keep them out.
