Salsalito has it narrowed to genus, but it won't be C. insularum because that species is endemic to Hawaii, and they don't export snails for the...
The limpet-like snail attached to your astraea is probably a Hipponix species. They are considered semi-parasitic, although they don't feed on the...
I think salsalito was going to post this link for you: The Sea Slug Forum - Tritoniopsis elegans There's some good info on the species on this...
Can't argue with that. If he'll eat it, go for it!
The ones in the studies mentioned in the link I posted didn't eat algae, period. They all ate molluscs, crustaceans, and echinoderms, with a few...
LOL I noticed that too, quite a coincidence, indeed! :)
Unfortunately, sostoudt is probably right, your starfish is starving. I don't know about feeding him algae wafers, but you might try something like...
Well, not to doubt the Florida hitchhikers site, but that last pic looks like the mantle of a Spondylus, or Spiny Oyster. I may be just looking at...
Some people don't like vermetid snails, so if your Thorn Latirus ate them, I guess they could be considered beneficial. Other than that, they aren't...
Yeah, that's a Thorn Latirus, Opeatostoma pseudodon. The whole family (Fasciolariidae) is predatory, mostly on other molluscs. This species shows...
There are a few snails that will eat them. I'm not sure if the Bumblebee Snails that are sold to the hobby will eat them, but some of their...
It's not a sea hare. It looks to be a sea cucumber of some kind, as the others suggested. It will be one of the filter feeders rather than the sand...
Nah, the snorkels on Nassarius are NOT normally red, which is why I was interested to see what kind of snail it was. Quite a few different snails...
Well, let's see a pic of the snail......!
Hi Curt, Don't really know Spiffyguy, just knew that he had some good photos of a polyclad flatworm that came out of his tank. I didn't know he had...
The shell moving does sound like an octopus, the but description sounds more like a Polyclad Flatworm. Just perchance the shell was there by...
Or like a gazelle taking down a cheetah, lol. It's an Aeolid nudibranch, and while not all nudi's are harmful, most of the ones in this family feed...
Yep, it's a Stomatella. You can see the flattened shell on its back in the pic, although it's only about half as big as the animal (or less). They...
Hard to say which species, but it's a polychaete worm. Lots of different species reproduce in this way, usually synchronized by the season and lunar...
Epitoke. It's the reproductive part of the worm that breaks off and swims up to the surface to meet the others that apparently didn't show up....
