Such crabs wear shells on the backs like the hermit crab, however the animals store titled 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

In the event that this type of crabs try competitive I could definitely bring her or him back toward shop and just have something far more appropriate to own my personal 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.

That crab is much big and competitive and try dominant during this “interaction”. Small more passive crab is the one I afterwards watched launching small larvae later in the day (I was shining a torch involved). He’s got produced several times already. I can not apparently see an answer on when they dioecious or hermaphrodite in my own courses (I’ve instructions by the Fenner, Delbeek and Sprung, Tullock, et al). I am aware this isn’t out-of world shattering pros, but I was only interested. Thanks ahead of time! I think I have an account your but it is according to California species (approximately pertains to tropical variety too). This is the address Personally received today away from a part out of mine Dr. Robert Toonen Secretary Lookup Professor, College out-of Hawaii during the Manoa University off Ocean and you can Earth Technology and you can Tech, The fresh Hawai’i Institute away from Marine Biology I am hoping it will help.

I have never elevated any of the popular tank kinds (for example blue- or purple-legs), however, I’ve increased several of the regional California variety

It will correlate together with your findings: “There was a lot of variability among other hermit crabs within their mating behavior, however, I’ll attempt to leave you certain practical generalizations. At the least brand new larvae is relatively easy to increase by comparison to many inverts. Which have one to exclusion, all hermit crab kinds in which I am familiar brood its larvae on the outside (however, when you look at the shell) up until it complete the nauplius degree (early stage larvae, just like a baby brine shrimp), this era may vary ranging from on the step one and you will 1 year, with respect to the variety. The brand new female after that discharge either zoea or megalopae (simply fancy terms for lots more-and-old larval amounts) and this typically feed on phyto- and zooplankton.
