-“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 such crabs are aggressive I can of course take him or her back into store and have anything a great deal more suitable getting my tanks

Marine Hermit crab reproduction methods – 7/ Hello WWM Crew, I’m a long time reader and fan of sugar daddies Miami FL 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.

You to definitely crab is significantly big and more competitive and you may was prominent with this “interaction”. Small a lot more couch potato crab is but one We later on watched launching lightweight larvae in the evening (I happened to be radiant a torch involved). He’s produced several moments already. I am unable to frequently see a reply regarding if they’re dioecious or hermaphrodite in my guides (I have books because of the Fenner, Delbeek and you may Sprung, Tullock, ainsi que al). I understand this isn’t off earth smashing characteristics, but I became simply curious. Thanks beforehand! I believe We have an answer for your but it is according to Ca kinds (about relates to exotic varieties also). This is basically the answer I know gotten now of a part from mine Dr. Robert Toonen Secretary Lookup Teacher, University away from The state from the Manoa University from Water and you may Planet Science and Technical, The fresh new Hawai’i Institute out-of Marine Biology I’m hoping it will help.

We have never ever increased the well-known tank kinds (particularly blue- otherwise reddish-legs), however, We have elevated many of the regional California varieties

It can associate with your results: “Discover a large amount of variability among more hermit crabs within mating choices, but I shall try to leave you certain practical generalizations. At the least the latest larvae is actually relatively easy to boost in comparison to many inverts. Having that exemption, all hermit crab varieties with which I am familiar brood their larvae on the outside (but within the shell) until it finish the nauplius stages (initial phase larvae, exactly like a child brine shrimp), this period may vary anywhere between regarding the 1 and you will 1 year, according to variety. New people after that release either zoea or megalopae (simply really love terms to get more-and-earlier larval levels) and that generally prey on phyto- and you may zooplankton.
