These types of crabs don shells on their backs such as the hermit crab, although animals store titled her or him “furry crabs”

-“Hairy” hermit crabs- I just purchased two medium sized (approx positivesingles-app 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 this type of crabs was competitive I’m able to needless to say get him or her right back into the store and have one thing even more appropriate to possess 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 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 much huge and much more competitive and you can is actually principal with this “interaction”. Small so much more inactive crab is certainly one We later on saw releasing smaller larvae in the evening (I found myself radiant a flashlight with it). He’s got produced one or two minutes already. I am unable to apparently get a hold of a response regarding the if they are dioecious otherwise hermaphrodite in my own courses (I’ve books by Fenner, Delbeek and you may Sprung, Tullock, mais aussi al). I’m sure that isn’t away from planet smashing strengths, however, I was only curious. Thank-you beforehand! I do believe We have an account you but it’s according to California varieties (around applies to tropical variety too). This is actually the answer I know obtained now away from a member from mine Dr. Robert Toonen Assistant Search Professor, College or university regarding The state on Manoa College or university regarding Water and you will Planet Technology and you will Technical, New Hawai’i Institute out of Marine Biology I really hope this will help.

I have never ever raised some of the well-known tank types (such as for instance bluish- otherwise reddish-legs), but We have raised a number of the regional California variety

It will correlate with your findings: “There’s quite a bit of variability among some other hermit crabs within mating conclusion, however, I’ll try to leave you some sensible generalizations. At the least new larvae try relatively simple to increase by comparison to the majority inverts. That have one to exception, all hermit crab kinds with which I am familiar brood the larvae externally (however, into the shell) until they complete the nauplius stages (initial phase larvae, just like an infant brine shrimp), this era may differ ranging from regarding step 1 and you may one year, with respect to the varieties. Brand new females following release possibly zoea or megalopae (simply enjoy conditions for lots more-and-old larval levels) and this generally feast upon phyto- and you can zooplankton.
