Growth on base of frogspawn?

[Anovack]

What is this long growth on the base skeleton of my frogspawn? Is it some kind of snail like you see on snails shells sometime?

A small filter feeder. Most likely a feather duster or something similar. Harmless. They don't get much bigger than that.

If you look to the left a little I believe that is where a new head wants to start. I think that because when my blues are on that pin prick lights up the same color as the others. Will this effect growth?

It's a vermetid snail. They cast out a net and filter feed from the water. They can irritate stony corals but are otherwise harmless. If you accidentally stir up some detritus in the tank you will be able to see their nets as they catch the particles.

It's too small to be a vermetid. I have both in my tank. That guy is harmless, where vermetids are a nuisance.

Are you sure? Vermitid is an entire family rather than a single species. We just lump them all together and call them vermetid snails because it's easier and they are all pretty much the same.

Well, either way harmless. I'll look at the one on my hammer coral when I get off work...but they don't overwhelm and spread through the tank so I doubt it's a vermetid. Obviously isn't the spiral shelled variety if it is. Those are the worst.

That's definitely a type of vermetid and they're harmless. I have ones that look exactly the same.

Harmless to a point, they will agitate sps corals causing problems with them.

Vermetid snails are bad for stony corals, coral crabs keep em in check

I've read that before but the ones in my tank even near all my sps have no effect

It's the spiral buggers you need to worry about. My reef is infested with them.
