    Whelks?

    Regrettably a lot of LFS aren't capable of distinguishing good & bad snails. I can't either without photos.... ;-) But from what you've said it seems likely that you do have predatory snails so baiting them out is a very good idea.

    What are these critters?!? Worms?

    There's not much to add. They show up & have population explosions then as the food supply is used up they die. In nature they're very common - I've found thousands in field samples. They're grazing on the algae-bacterial film-micro inverts that live on the glass. Cleaning the glass more...

    Yellow nudi or seaslug? Reef Safe? HELP!

    Hi all -- It's a saccoglossan opistobranch (not a nudi) in the genus Elysia. There are several yellow species. Elysia flava from the Caribbean/Mediterranean is mostly all yellow, Elysia obtusa from the Indo Pacific is yellow with white lines along the edges of the flaps, and Elysia subornata...

    Snail & worms

    All very true but I do need to see images to really understand what (or who) we're talking about here. You were pointing a light at the snail & worms were moving towards it? Many polychaetes & other animals are responsive to bright lights at night. Spawning is timed to the full moon...

    Is this a Spaghetti or Hair worm?

    :whip::whip::whip: 3 lashes with a wet fireworm! Although, perhaps we should be more concerned about your diet than anything else......:wink:

    Is this a Spaghetti or Hair worm?

    Oh Krish, how could you? Comparing a cute little wormie to your semi-digested lunch! :drama: Actually it's a Cirratulidae, AKA hair worm, although it is still a beneficial detritivore. There's a group of feeding appendages up by the head which gathers food. The rest of the appendages...

    Help IDing crabs

    It's thought that they live a year or two in the wild. It would be interesting to hear from reefers who have kept them for longer in their tanks. One problem with buying wild-caught animals is that it's hard to know how old they are when you get them. A critter could be 2 months old & last...

    Help IDing crabs

    Not all emeralds are model citizens. It's not uncommon to find posts complaining about rogue emeralds. Keep it well fed by adding nori if the level of algae in your tank gets low. Also, the spoon-tipped claws aren't really a good clue to feeding behavior. Many of the little xanthids that...

    Giant bristleworms spawning in my tank!?!?!

    Cut down on feeding for a while then drop some silversides into the tank. The big worms should come out and you can grab them. Wrapping the meat in cloth with a coarse mesh (like tulle) that the worms will crawl into also helps trap them. Fireworms are dioecious - they need both males &...

    Cleaner shrimp playing dead??Or just is

    No insight, just the obvious - gotta make sure the critters are healthy before you buy! Kyle, thanks for being willing to share and letting others learn from your experience.

    Help with bristle worms

    I'm really the wrong person to ask about removal - I like bristle worms! Throw out those boring old corals & fish & bring in the worms, that's my motto. ;-)) Arrow crabs are known predators but they also go after anything else they can catch. Wrasses are good. Baiting them out works well...

    shrimp id please

    it's also been found in Samoa. So either it's rare over a wide area or not very often noticed. do you know where your monti came from, noskills?

    shrimp id please

    Oh, I just love these little guys! It's actually a hermit crab that instead of walking around in a shell it lives in an old christmas tree worm burrow. The name of this particular species is Paguritta corallicola. Those feathery antennae you noticed? They use them to catch food particles...

    Alien in my tank!! What is it????

    it is unless you overdose. Too much and other animals will be affected as well. There are tons of posts about flatworm exit and other ways to get rid of flatworms along with their pros & cons on this & other boards.

    Alien in my tank!! What is it????

    Hi guys -- Everyone who said Flatworm stand up & take a bow. It looks a bit different than the usual mollusc-eater which we call Pericelis. Pericelis will swallow small snails whole, digest out the animal, then spit out the shell. With bigger molluscs it will evert it's proboscis, secrete...

    Cool Pics

    clubbed brittle star Today's pics were taken by Ollie Mengedoht (Beastiependent on the boards), an ardent crab-lover and photographer extraordinaire. Brittle stars & serpent stars all belong to class Ophiuroidea in the phylum Echinodermata. The phylum name means "spiny-skin" while the class...

    Strange creatures in my tank

    What reefers call bristle worms is what the rest of the world calls fireworms. A couple of the species will eat corals; one is a specialist predator on gorgonians in fact. However, these species very rarely show up in aquariums. They're big & conspicuous since they don't hide. 99% of the...

    Id of This please???

    Fishy's right - one of the many small species in the family Asterinidae that reproduce by splitting in half. Most of them are harmless micro-grazers but some of the species are predators that eat corals. The predators show up much less frequently than the harmless ones. You'll need to watch...

    Your pick for some really intresting inverts.

    Okay, a little more seriously this time. I think it's a trade off between reef safe & creepy crawlie/interesting. Crabs are fascinating in color & shape but many of them are not to be trusted around soft corals. There are some very colorful sea cucumbers but some of them are toxic & can nuke...
