These crabs wear shells to their backs for instance the hermit crab, but the pets store named her or him „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 such crabs are competitive I can definitely get them back into the store and have now some thing way more suitable to possess 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 much big and more aggressive and is actually prominent with this „interaction”. The smaller a lot more passive crab is certainly one I later spotted releasing lightweight larvae later in the day (I was shining a torch inside it). He has got spawned two minutes currently. I can’t apparently come across a response regarding if they’re dioecious otherwise hermaphrodite within my books (I have instructions by the Fenner, Delbeek and you will Sprung, Tullock, ainsi que al). I know this isn’t out of earth shattering benefits, however, I happened to be simply curious. Thank you so much ahead! I think We have an answer for you however it is considering California types (more or less applies to tropical species too). This is the respond to Personally, i gotten today from a part regarding exploit Dr. Robert Toonen Assistant Browse Teacher, College or university out-of Hawaii during the Manoa University out of Sea and you will Earth Science and Technical, The newest Hawai’i Institute away from Marine Biology I hope it will help.

We have never elevated all prominent aquarium types (such as for instance blue- or red-colored-legs), however, We have elevated several of the regional California types

It will correlate with your findings: „There clearly was a large amount of variability certainly other hermit crabs within mating conclusion, however, I will attempt to give you specific sensible generalizations. At least this new larvae try not too difficult to boost in comparison to most inverts. Having you to definitely exception, all the hermit crab varieties that I am common brood its larvae on the outside (but from inside the cover) until they finish the nauplius values (early stage larvae, similar to an infant brine shrimp), this era may differ anywhere between throughout the step one and you will one year, depending on the varieties. New ladies next launch either zoea or megalopae (only really love conditions for hoe te zien wie je leuk vindt op okcupid zonder te betalen much more-and-elderly larval amount) and therefore generally speaking feed on phyto- and you will zooplankton.
