Pix & ID: Critters that come in your rocks: the good and the bad.

Tanks been running 2 months

Tanks been running 2 months

After two months of having it running I saw something growing. Could y'all help me identify it?

Any help on these two would be helpful, I tried to do a google search but just couldn't seem to come up with a proper way to phrase this snail like creature below. Round shell that is shaped like a pyramid with a point in the center, sucks algae like a snail, and has two weird horn looking protrusions from inside his shell.

Second ID help is these white and black or possibly white and green worm looking deals that are attached to the rockwork that just sway in the flow. Really skinny and small so it is hard to get an accurate color from my crappy eyesight. I have hermits and an urchin that frequent that area but it looks like they always leave those things alone.

Can't help you with the snail, but those "worms" are mini brittle stars catching food. They're a good thing to have. :-)

PS... Thinking your snail may be a limpet. Nothing wrong with it, I'm thinking.

Awesome thanks for the quick replies, glad the brittle stars are a good thing, I have quite a few on that rock and the prospect of removing them all given their small size did not seem fun. From a quick image search of limpets, that appears to be what it is, thanks! 2/2 on the unknowns being beneficial, nice.
 
Small black thing--a worm?

Urchin? Does it come out? I mean it totally looks like an urchin from here but pics can be deceiving.

I just spotted it for the first time after I reorganized the rock, and I haven't seen it move. I thought urchin, too, but because it hasn't moved from there in 2 days I'm thinking not an urchin or dead.

The first two pictures are of a limpet. (harmless) The third one is of micro brittle stars hidden in the rocks. (harmless)

If it hasn't moved at all, it might be a barnacle of some sort. That's what those white protrusions on the rocks look like at least.
 
Can anyone tell me what these "Medusa" looking things are? They just showed up one day!
Thanks in advance!

That looks just like a gorilla crab, I do get the visual of porcelain crabs and gorilla's mixed at times though.

I am sure a crabbie patty person will be able to identify it quickly.
