Dude, if I'm not mistaken that's a cyrolanid... very bad. As in pure Eeeevil.

Sally Lightfoot?
Not a Sally Lightfoot, that I do know. What he is, I do not know.
Sally's are spindley and lower profile. Colors vary, but generally are adorned with bright racing stripes on legs and bady rims. Slim. (that is body rims, I'm no scientist, either)

I want to guess he's a decorator crab? Be careful, if so. I've heard they will use anything they can to accessorize themselves.

JUst curious about the carribean mushroom are they bad/good?

Why is this thread not sticky anymore? I love this thread.

 

[reckler]

I would like to know what this thing is. It is about a 2 cm across and about 2.5 cm tall. I hope the pic is good enough to see it. It is the thing with the tenticals.

This may be Spagetti worms, or whatever they call them. I have no idea what they are. And there is a snail that is about an 1.25" long that came out of the lr that i don't know what it is called.

 

[bang guy]

The Snail is either a true Limpet or a Keyhole Limpet. The Keyhole will have a hole in the top like a volcano.
If I were to guess I'd say you have a Keyhole Limpet.

i had a pistol shrimp hitchhike along and its probably 1/5 an inch right now.... only seen him 3 times.... but i was curious how long it will take for him to get bigger and start coming out more?

It does have a hole on top. Are they safe? He seems to not bother anything. Although he is extreamly slow, well compared to my turbo snail.

Occationally they will stip the outer layer off a leather coral. Typically they eat algae, Hair, diatoms, coralline, etc.

Some Snails that were eating my new Botton Poylops. And some kind of worm.

 

[bang guy]

The Snail on the right is a Sundial type snail. They are known Zooanthid predators. I'd destroy it.
The left snail looks like an Astreae to me. If so it couldn't eat your coral. If you see it actively eating your coral then I don't have any idea what type of snail it is.
The worm is a common Fireworm and is a beneficial scavenger.

Here's the post about the sundials.

Collonista are "mini-Turbo snails." They are seldom purchased by hobbyists, but are relatively common in reef tanks anyway, because they appear to hitchhike in on live rock or in some live sand. When hobbyists first see them, they presume them to be "baby" grazers of some sort. Instead, they have some of these animals. They reach a maximum adult size of about 1/4th inch (6 mm) in height and diameter. They are often tan to white and have mottled brown color patterns on the shell. They can be distinguished from all other Trochoideans by their small size and the presence of a small pit or hole in the center of the calcareous operculum that plugs the aperture. They reproduce well in aquaria, and are quite good grazers. If present in large numbers, they may effectively replace all other grazers in our systems.
