This type of crabs don shells on the backs for instance the hermit crab, nevertheless the animals store called him or her “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 could however simply take them straight back into the store as well as have one thing way more suitable to have 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.

One crab is much big plus aggressive and you will was prominent during this “interaction”. Small alot more inactive crab is one We later saw launching tiny larvae in the evening (I was glowing a torch with it). He’s produced two moments already. I am unable to frequently look for an answer from the if they are dioecious or hermaphrodite during my guides (I’ve books by Fenner, Delbeek and Sprung, Tullock, mais aussi al). I am aware it is not from planet shattering pros, however, I became merely interested. Thanks in advance! I think I have an answer for your but it is centered on California kinds (about applies to warm species too). This is basically the answer Personally obtained today from an associate from exploit Dr. Robert Toonen Assistant Browse Professor, College or university from Their state at the Manoa College of Water and you will World Science and you will Tech, The newest Hawai’i Institute from Aquatic Biology I really hope this will help.

I’ve never ever elevated any of the well-known aquarium varieties (particularly blue- otherwise yellow-legs), but You will find raised a number of the regional Ca variety

It will associate together with your findings: “Discover quite a bit of variability among different hermit crabs within mating decisions, but I shall make an effort to make you certain realistic generalizations. At the least the fresh larvae are not too difficult to increase by comparison to most inverts. With one exception to this rule, every hermit crab types that I am common brood the larvae on the exterior (however, inside the layer) up to it complete the nauplius levels (early stage larvae, exactly like a baby brine shrimp), this period may vary between regarding the step one and one year, depending on the variety. New people next release often zoea or megalopae (simply really love words for more-and-elderly larval amount) and that generally speaking feed on phyto- and you can zooplankton.
