Help! I’ve been attacked!

By Hydroids! I read in a book called Dwarf Seahorses by Alisa
Abbott and I was told by a good friend these are evil to dwarf
seahorses. I wasn't really worried about it 'till yesterday when I was
feeding the little guys and noticed there were a lot more than before!
They are talking over my nano! Anyway, doing a little google search,
I found out limpets will eat them, and they come on live rock. So, I
must have them in my big tank, 'cause I've got very few hydroids in
there (I rarely see them, anyway). So, what is a limpet? Any body
know? I'm going to start collecting crawly things from my sump, but
if any body has a hydroid eater I could buy or borrow, I would really
appreciate it!

Thank you very much, Kevin. Your offer is very generous. I think I
have what I need in our big tank, though. We don't have any in there,
and I use the same system water. So, I think something in there is
eating them. Yesterday, I picked out a bunch of the slug looking
things, that is the only thing I can think of that I haven't seen in the
small tank. Do limpets look like this:

are the star looking things in the first picture what you are talking about? Are they snail or slug style creatures or what? newbie out

Suzy -

I didnt scrape my glass for almost a month trying to see how big I could get my hydroids, and mine never got that big! What are you feeding those things?!?!

Suzy,

The "slug like" creatures look like Stomatella Snails to me.

[It] is a desirable herbivore.  When alarmed by a predator it can shed the tip of its meaty foot, like a lizard shedding its tail.

I have actually seen one shed its foot while being attacked by a wrasse.  It was cool.  The wrasse got a meal and the snail crawled away.  They are amazingly fast (for a snail)

Suzy,  I saw some limpets in a tank at Increadible pets a month ago.  They looked like they were there by accident so I don't know if they are still around.

Something in our big tank must be eating them. Everything is the
same. Do you think the Stomatella Snails eat 'em? I'd go for the
Keyhole limpet, but I was hoping to add sps to this tank.....

I WANT IT ALL!!!

quick stupid.... whats a sps?

Euphilia anchora, Euphilia paradivisa, Euphilia frogspawnius, ect...

The Incredible Mr. Limpet, if memory serves...

And how about Whitish bubblicious?

I used to get that all the time when I was kid.  You chew that one square of gum for 8 hrs nonstop and it not only looses it's flavor, but also its color

It's not that I am picky or obsessive, but I think you meant Euphyllia.

My spell checker didn't like either of those spellings
He asked "without looking it up" so I followed his rules and I can't spell to save my life.
