    Normally crabs & shrimp constantly groom themselves to keep stuff from growing on them. This hermit may have lost it's grooming appendages - that's why it's overgrown. When the crab molts the algae will be shed along with the old exoskeleton.

    A sea cucumber almost crashed my tank

    Not weird at all. As you noticed, it was stressed and that's a typical response. Good thing you were observant & got it out in time to save your corals!

    Leslie's Picks on CUC's

    Serpent stars & brittles are all ophiuroids. The only difference is that the serpents have smooth or relatively smooth arms with inconspicuous spines while the brittle stars have conspicuous arm spines. What's more important is the food preference & behavior of the individual species...

    A sea cucumber almost crashed my tank

    Thanks for posting the link, Sid. I can't overpraise Rob Toonen's and Ron Shimek's columns on inverts. This cuke article by Rob is a great example. Full of good information clearly stated, it addresses aquarium issues, provides data from both the hobbyist side & the science side, tells you...

    Looks like a spider???

    Hi Phil -- That's one lateral (side) part of a crab, showing the 4 legs & big claw. If you can get a better image of it we might be able to give you a better idea of the species and it's feeding habits.

    Shrimp ID Confirmation

    Art's pic is of either a male or a young one with a reduced pigment pattern on the abdomen. Krish had a plump female probably with eggs and a strong pigment pattern.

    Bristle worms and fireworms

    I'm surprised too. A worm of any kind is usually a nice chunk of protein for an anemone. Looks like you spend a lot of time in the water. I'm jealous!

    Tuxedo Urchin vs. GSP

    Two of the reasons urchins decorate themselves is as camouflage and to protect their soft tissue from UV rays which can damage them. Your urchin is more than capable of pruning the GSP on its own but you won't seriously harm it by carefully pulling off the polyps. Do it gently so not too many...

    Critter Oddities

    It's not uncommon for worms to have abnormalities either from problems in development or regeneration after being wounded. My favorites are the "pinheads" - where the head region has been bitten off and the head is regrowing but it's much smaller in diameter than the rest of the body. CBs are...

    Invert compatibility?

    NC2WA - are you sure you're not confusing cowries with cone snails? Cowries aren't poisonous but the cones are. Some posters have complained that their purple lobsters are obnoxious predators which go after a variety of species including other shrimp.

    OUCH.....Bristleworms!

    I may kid about petting fireworms but believe me, I stay as far away from them as possible! As for true stories, well.... I once knew a guy (name is withheld to protect the stupid) who liked to collect stuff for his aquarium. Not too bright. Found a fireworm, didn't know what it was but...

    Shrimp ID Confirmation

    No problem, Krish. First off, I really enjoy searching for ids (actually my favorite type of reef question) and second, it's a common species. Periclimenes rathbunae, the sun anemone shrimp. Native to the Caribbean, it mostly hangs out with the sun anemone Stochodactyla helianthus but will...

    Pistol Shrimp ID

    That's a really common color pattern among the small rock-dwelling alpheids. I've seen lots of these living in dead coral rubble from the Indo-Pacific, Hawaii, and the Caribbean. Without knowing where it originally came from I hesitate to put a name on it. But, the good news is that they do...

    Please help me ID, thanks

    IPisces & Boomer are right, it's a dorid nudibranch. Definitely not Chromodoris rubrocornuta, color & papillation on the back are way different - The Sea Slug Forum - Chromodoris rubrocornuta Not a Chromodoris at all. The members of that genus usually have long bodies and smooth dorsums...

    Leslie's Picks on CUC's

    Frankie, the worms I've occasionally seen offered for sale as CUC are cirratulids (hair worms). I'd love to hear from a dealer to know whether they're specifically targeted by collectors or are accidental by-catch or if someone is successfully breeding them. As some of the common cirratulids...
