These crabs wear shells on the backs like the hermit crab, nevertheless the animals store called them „hairy crabs”

-„Hairy” hermit crabs- I just purchased two medium sized (approx 3″ shells) „hairy crabs” from my favorite fish store. I have looked at everything I can find on the internet pertaining to these crabs to no avail. Since I rely on info I obtain from the internet to learn about new purchases I am stumped by the lack of info on my crabs. I placed one crab in my 55g reef tank with LR and one coral. It also has a large yellow tang, 7 assorted damsels, a brittle star and a goby. Is the crab a danger to any of these already established animals. The other crab went into a 75g tank with a blue tang (approx 8″) and a carpet anemone. I am just stocking this tank as it’s only 3 months old. Also since they seem to be of the hermit family should I keep several larger shells available for them to use as homes. Thanks for all the info your website brings to those of us who are less than marine biologists. Janie

When the such crabs try competitive I can naturally simply take her or him right back with the store while having things much more appropriate having my tanks

Marine Hermit crab reproduction methods – 7/ Hello WWM Crew, I’m a long time reader and fan of the site. Glad to hear> This is my first time writing (because the site is so darn comprehensive and all my other questions have been answered before! I have 2 scarlet reef hermits in my 10g Nano and just want to know if they are hermaphrodites or distinctly male or female. My guess is the former, but their behavior makes me wonder. I think I have seen them mating. They both went down into a big, secluded hole in the live rock and faced each other and sort of interlocked legs and came partially out of their shells so the soft parts were exposed.

One crab is significantly larger and competitive and you will try dominant with this „interaction”. The smaller so much more passive crab is but one I later noticed initiating small larvae at night (I happened to be shining a flashlight inside). He has got spawned a couple of minutes already. I can’t apparently pick an answer on if they’re dioecious or hermaphrodite during my courses (We have courses of the Fenner, Delbeek and Sprung, Tullock, et al). I know that isn’t out of world shattering pros, however, I was just curious. Thanks beforehand! I do believe We have an account your but it is predicated on Ca types (around pertains to warm varieties too). Here tinder-ondersteuning is the address i acquired now out of an associate regarding mine Dr. Robert Toonen Assistant Research Teacher, College away from The state at the Manoa School away from Sea and you will Planet Science and you may Technology, Brand new Hawai’i Institute from Marine Biology I really hope this will help to.

You will find never ever increased some of the common tank variety (including bluish- otherwise purple-legs), but I have elevated several of the local California varieties

It will correlate together with your conclusions: „There clearly was quite a bit of variability one of some other hermit crabs within their mating decisions, however, I am going to try to leave you particular practical generalizations. No less than the brand new larvae are relatively easy to increase in contrast to many inverts. With that exemption, every hermit crab kinds that I am common brood the larvae externally (but during the cover) up until they complete the nauplius values (initial phase larvae, exactly like a baby brine shrimp), this era can differ ranging from throughout the 1 and you can one year, according to the types. The newest people then launch often zoea otherwise megalopae (only fancy words to get more-and-earlier larval amounts) and that generally prey on phyto- and you can zooplankton.
