This type of crabs wear shells to their backs like the hermit crab, although animals store titled them “furry 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

If these crabs are competitive I’m able to however take her or him straight back to your store and possess things significantly more compatible to have 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.

One to crab is a lot large and much more aggressive and you will is actually dominant during this “interaction”. Small a great deal more passive crab is just one I after watched initiating lightweight larvae at night (I happened to be radiant a flashlight involved). They have produced two moments already. I am unable to apparently find an answer about when they dioecious otherwise hermaphrodite inside my books (We have guides by the Fenner, Delbeek and you will Sprung, Tullock, et al). I know that isn’t of planet smashing benefits, but I found myself just interested. Many thanks in advance! I think I have an account your but it’s according to California variety (around pertains to warm species too). This is basically the respond to i obtained now off an associate away from exploit Dr. Robert Toonen Secretary Research Professor, College or university off Hawaii on Manoa University off Ocean and you can Planet Research and you will Technology, This new Hawai’i Institute away from Aquatic Biology I’m hoping this will help to.

We have never ever increased the well-known tank kinds (instance blue- or reddish-legs), but You will find raised a number of the regional Ca species

It can correlate along with your conclusions: “There is a lot of variability certainly some other hermit crabs in their mating decisions, however, I am going to you will need to give you specific sensible generalizations. At least the latest larvae was not too difficult to increase in contrast to most inverts. That have you to definitely exemption, most of the hermit crab varieties in which I’m familiar brood the larvae externally (however, in the layer) up to they complete the nauplius degrees (initial phase larvae, similar to an infant brine shrimp), this era may differ ranging sugar daddies from from the step 1 and you will 1 year, with respect to the types. The newest women next launch either zoea otherwise megalopae (simply fancy terms for much more-and-more mature larval level) and therefore generally feast upon phyto- and you will zooplankton.
