These crabs don shells on their backs like the hermit crab, but the pet store entitled them “furry crabs”

I believe You will find an account your but it’s according to Ca varieties (roughly relates to warm variety also)

-“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. If these crabs are aggressive I will definitely take them back to the store and get something more compatible for my tanks. 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

I’m sure this isn’t of planet shattering pros, however, I found myself simply interested

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.

You to definitely crab is a lot large and much more aggressive and you can are prominent in this “interaction”. Small significantly more couch potato crab is the one I after noticed initiating little larvae at night (I was radiant a torch involved). He has got spawned several minutes already. I can not seem to pick a response on when they dioecious or hermaphrodite within my courses (You will find guides because of the Fenner, Delbeek and Sprung, Tullock, mais aussi al). Thanks in advance! Here is the address Personally, i obtained today regarding a part out of mine Dr. Robert Toonen Assistant Look Professor, University of The state at Manoa School se puede consultar aquí of Sea and you will Earth Research and you will Tech, The fresh Hawai’i Institute off Marine Biology I’m hoping this helps.

It will correlate with your conclusions: “You will find a substantial amount of variability certainly one of some other hermit crabs within their mating behavior, however, I’ll make an effort to leave you certain realistic generalizations. About the latest larvae is actually not too difficult to boost in contrast to the majority of inverts. I have never ever elevated all common aquarium kinds (eg blue- otherwise purple-legs), but I’ve elevated several of the regional California kinds. That have that exception to this rule, all of the hermit crab species that I am familiar brood the larvae on the exterior (but in the shell) until they complete the nauplius degree (initial phase larvae, just like an infant brine shrimp), this period can vary ranging from throughout the 1 and you may one year, with regards to the variety. The new women next release either zoea or megalopae (only really love terminology for lots more-and-more mature larval stages) hence usually feed on phyto- and zooplankton.
