-“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

When the such crabs are competitive I will obviously take her or him straight back on the store and also things much more compatible having my 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 sitios de citas ecuestres gratis 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 crab is significantly larger and a lot more aggressive and you may is actually dominating in this “interaction”. Small even more inactive crab is just one I afterwards saw opening smaller larvae at night (I was shining a torch in it). He has got spawned a few minutes already. I am unable to appear to come across a reply regarding the if they’re dioecious otherwise hermaphrodite inside my courses (You will find courses because of the Fenner, Delbeek and you will Sprung, Tullock, ainsi que al). I’m sure that isn’t off world shattering importance, but I happened to be only interested. Thank you so much ahead of time! In my opinion I’ve an account you but it’s according to Ca variety (more or less applies to exotic kinds as well). This is the address i obtained now regarding a part off exploit Dr. Robert Toonen Assistant Lookup Professor, University out of The state at Manoa School away from Water and Environment Research and you will Technology, The Hawai’i Institute from Aquatic Biology I am hoping this helps.

You will find never ever elevated all common aquarium variety (such as for example bluish- otherwise red-colored-legs), but You will find elevated many of the local Ca kinds

It does associate with your findings: “Discover a large amount of variability certainly other hermit crabs inside their mating choices, however, I’ll just be sure to leave you particular realistic generalizations. About the brand new larvae is relatively simple to boost in contrast to many inverts. Having that exemption, all of the hermit crab species in which I am familiar brood its larvae on the outside (however, inside the shell) up until they finish the nauplius grade (early stage larvae, just like a baby brine shrimp), this era may differ between throughout the step one and you will one year, depending on the varieties. The latest females then discharge possibly zoea otherwise megalopae (merely love words for much more-and-old larval amounts) which generally speaking feed on phyto- and you may zooplankton.
