These types of crabs don shells on the backs like the hermit crab, but the dogs shop entitled her or him “hairy crabs”

I think We have an answer for your but it is centered on Ca varieties (approximately pertains to exotic kinds as well)

-“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. If these crabs are aggressive I will definitely take them back to the store and get something more compatible for my tanks. 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

I am aware this isn’t off planet smashing benefits, but I happened to be just interested

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 significantly huge and more aggressive and you will is actually principal with this “interaction”. Small significantly more passive crab is but one I after noticed opening little larvae at night (I found myself shining a flashlight on it). He’s got produced several times currently. I can’t appear to get a hold of a response in the if they are dioecious or hermaphrodite in my own instructions (We have courses by the Fenner, Delbeek and Sprung, Tullock, mais aussi al). Thank-you beforehand! This is the address i gotten today from a member off mine Dr. Robert Toonen Secretary Research Teacher, College out of The state on Manoa University away from Water and you will Earth Research and you may Tech, The new Hawai’i Institute out-of Aquatic Biology I really hope this helps.

It will associate with your results: “There is a substantial amount of variability one of other hermit crabs in their mating decisions, but I will try to give you some reasonable generalizations. At the very least this new larvae try relatively easy to increase by comparison to the majority of inverts. I’ve never raised the popular tank varieties (such as for instance blue- otherwise reddish-legs), but We have raised a number of the regional Ca varieties. Having that exception, all of the hermit crab varieties with which I’m common brood their larvae on the exterior (however, inside shell) up to it finish the nauplius level (early stage larvae, the same as a baby brine shrimp), this nazwa użytkownika militarycupid era can differ ranging from from the step one and you can one year, according to varieties. The brand new girls up coming launch either zoea or megalopae (merely admiration words for more-and-elderly larval degrees) which usually prey on phyto- and you will zooplankton.
