It's not really a whelk, although it may be related to them. It could be a worm-eating miter species (Strigatella), but I believe it's a Dove Shell,...
It's a polychaete of some sort. It looks a lot like a Palolo worm, a delicacy in much of the Pacific. You could always saute it with onions and eat...
Like Salsalito, I had multiple species of brittle stars and serpent stars in my 55 at the same time, and they never seemed to bother each other. I...
Really? I never realized there was a potential problem. Which is a threat to the other? Don
Sorry to hear that. That's what usually happens, though. It's probably been starving for quite a while before you got it. Cheers, Don
About the only things that will nuke your tank are Sea Apples (and their close relatives) and phyllidiid nudibranchs (uncommon in reef tanks, but one...
Yup, those are definitely pyramidellids, and you'll want to remove them. The vermetid won't hurt anything. Sorry if I confused any of you about the...
They're not all that hard to keep, assuming they don't get out of the tank. Different species will favor different foods, but mine would try...
OK, if the white spot is in the middle of its back, it's a Shield Limpet (Scutus). Most everyone agrees they are nice residents. The Sea Slug Forum...
There's a good chance it's a Scutus species, or shield limpet, rather than a nudibranch. Can you sometimes see a white line down its back?...
I've never had one break the glass, but then again, I had one hit the glass so hard it sounded like a rock hitting your windshield at 70mph. It...
It could be a limpet, or it could be something else. There are a lot of different snails whose feet are several times larger than the shell, when...
Yes, it's a eunicid, and they are normally bad news. Unless you just want to keep him as a neat predator in his own tank, you'll want to remove him....
That's true, because if you have one of the monster spotted flatworms, he'll eat any molluscs you have in the tank. Nevertheless...the critter in...
Hmmmm.....do you know how to post pics on Photobucket or one of the other sites that hosts photos? If you can do that, then copy and paste the IMG...
Yes, they are Ark Clams, probably either Arca zebra or Arca imbricata. You'd have to extract one and clean it up to tell for sure: Arca zebra...
They're actually chitons. Stomatellas won't ever attach themselves to the glass below the substrate. Chitons tend to do this quite a lot. If you...
Yeah, it's an algae grazer like the other nerites. This species probably isn't as likely to want to climb out of your aquarium as some of the...
Pagojoe does his best work late at night, so if you post in the morning you may have to wait a while for an ID, lol. It's Nerita albicilla. Yours...
Sure, I'll take him if you don't want to keep him. I usually keep the shells of snails that give their lives for the greater good of the tank, so...
