In my opinion I’ve an answer for you however it is centered on California species (about applies to tropical varieties too)

-“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 https://datingranking.net/pl/married-secrets-recenzja/ 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 understand this is simply not of world shattering advantages, however, I was merely curious

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.

That crab is much huge and more aggressive and is actually dominant in this “interaction”. Small a lot more couch potato crab is certainly one I afterwards noticed establishing lightweight larvae in the evening (I happened to be glowing a torch on it). He has spawned two times already. I can’t frequently pick a reply regarding if they’re dioecious otherwise hermaphrodite inside my books (We have books because of the Fenner, Delbeek and you can Sprung, Tullock, et al). Thank you so much ahead of time! This is basically the answer I personally obtained today out-of an associate off exploit Dr. Robert Toonen Secretary Research Professor, College or university of Their state at Manoa College or university regarding Ocean and you may Earth Technology and you will Technology, The latest Hawai’i Institute regarding Aquatic Biology I’m hoping this will help to.

It can associate along with your conclusions: “There is certainly quite a bit of variability one of additional hermit crabs in their mating conclusion, however, I will try to give you particular sensible generalizations. No less than the fresh larvae was not too difficult to improve in contrast to many inverts. I have never elevated the prominent aquarium kinds (such as bluish- otherwise yellow-legs), but We have increased a number of the regional California types. Which have you to definitely different, all the hermit crab varieties with which I am familiar brood its larvae on the outside (however, in the shell) until it complete the nauplius amount (initial phase larvae, just like an infant brine shrimp), this period can vary between regarding the step 1 and you may 1 year, according to kinds. The new females following discharge possibly zoea or megalopae (simply appreciation terms and conditions for lots more-and-older larval amounts) and therefore generally feast upon phyto- and you may zooplankton.
