Vermetid Snails?

[Charles Belisle]

I started an external refugium about 2 months ago. I have added copepods and some micro aglea. I noticed a couple weeks ago, some white deposits on the back of the refugium. Today it looks like these white deposits have hatched into long reaching stems. Please look at pictures - Are these vermetid snails? not - dealt with these in past. They are in refuguim only for now.

Yes, you guessed correctly

Or maybe

Vermited snails or something else?

Hi I have seen these little white vermited snail looking things populate the skeleton of my frogspawn coral and now my rock and back of the tank Are these vermited snails or some type of filter feeder? I have not seen any mucas feeding nets from them

They are spirorbid worms, not vermetid

I agree with this. They usually boom then die off. If they don't add a bumblebee snail or 2 and they'll slowly bring down numbers. They're also a decent vermentid snail preventative. Can occasionally kill very small sick snails though if very hungry

Thanks for replies - I will look to add bumblebee snail to refuguim. Do either affect copepods - was looking to any growth with them.

A bumblebee snail is a micropredator. Not sure about copepods, but they'd affect amphipod populations I'd assume
