I'm pretty sure I know what most of this is, but to be sure I figured I'd ask.

1. I'm thinking Red Gracilaria

2. Don't know on this one....Nas...snail?

3. I'm thinking some kind of conch

4. Urchin of some sort...

5. Not sure but it looks evil....some kind of parasite?

The urchin looks like a pencil urchin, though I have only a low level of confidence in that. Not sure of the others. Where did they come from?

The first snail looks like a mud snail.

The snails look like Ilyanessa obsoleta to me as well. They're often sold as Nasarrius by less reputable vendors, but they're a temperate snail, not tropical and they prefer cooler waters than our tanks. They're not detrimental to a reef tank, though. They probably just won't live as long as other snails due to the temperature.

would you consider using the snails?

pagojoe · 09/05/2008, 05:16 AM

The conch-like snails are Stramonita haemastoma, in the Murex family, and although they are tough and survive well in aquaria, they are predators on essentially all other snails as well as clams and barnacles. The Ilyanassa snails may have some natural resistance to predation by them, though, since they share some of the same habitat (or at least, their habitats may adjoin each other). Just about any other snail you put in the tank is liable to be eaten by the Stramonita. If these are the only snails you have in the tank, they may be OK together...especially if you can easily replace any of the prey snails that get eaten.
