These types of crabs don shells to their backs such as the hermit crab, but the animals store entitled him or her “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

In the event the these crabs was competitive I can naturally grab her or him right back with the store and possess things even more compatible to possess my tanks

Marine Hermit crab reproduction methods – 7/ Hello WWM Crew,<Hello there. Paul Mansur here today> 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 big and aggressive and is dominant with this “interaction”. Small far more inactive crab is one I afterwards noticed opening lightweight larvae in the evening (I found myself glowing a torch on it). They have spawned two minutes already. I can not seem to come across a reply regarding if they’re dioecious or hermaphrodite in my own courses (We have instructions because of the Fenner, Delbeek and Sprung, Tullock, et al). I know this is simply not away from environment shattering benefits, but I happened to be just curious. Thank you beforehand! I think You will find an account you but it’s considering California types (more or less relates to exotic varieties too). Here is the address Personally gotten now away from a part regarding mine Dr. Robert Toonen Assistant Lookup Professor, College or university out-of Their state within Manoa College or university out-of Water and Environment Technology and you will Technology, The latest Hawai’i Institute from Marine Biology I hope this helps.

I have never elevated any of the prominent tank varieties (such as for example blue- otherwise reddish-legs), however, You will find elevated a number of the regional California species

It will associate along with your results: “There clearly was a large amount of variability certainly one of additional hermit crabs inside their mating choices, but I shall try to leave you specific practical generalizations. About the fresh new larvae is relatively easy to improve by comparison to most inverts. Having that exclusion, the hermit crab kinds in which I’m familiar brood their larvae on the exterior (however, for the shell) up to they finish the nauplius amounts (initial phase larvae, exactly like mytranssexualdate daten an infant brine shrimp), this era can vary between throughout the step 1 and you will 12 months, depending on the variety. The fresh women up coming release often zoea otherwise megalopae (simply prefer terms for lots more-and-old larval amount) which usually feast upon phyto- and zooplankton.
