These types of crabs don shells on the backs including the hermit crab, nevertheless the pet shop titled them “furry 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 that this type of crabs is actually aggressive I am able to however take him or her back into the store while having one thing so much more appropriate getting 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 to crab is a lot big and a lot more competitive and you may try dominating during this “interaction”. The smaller much more couch potato crab is one I afterwards watched starting small larvae in the evening (I was radiant a flashlight with it). He has produced several moments currently. I can not frequently get a hold of a reply regarding if they’re dioecious or hermaphrodite within my courses (I’ve instructions because of the Fenner, Delbeek and Sprung, Tullock, ainsi que al). I’m sure this isn’t out of earth smashing characteristics, however, I was just curious. Thanks a lot beforehand! I do believe I’ve an account your however it is according to California variety (about applies shagleprofiel to warm species also). Here is the answer I know received now off a part from mine Dr. Robert Toonen Secretary Look Teacher, School away from Their state in the Manoa College out-of Water and you can Environment Research and Technical, New Hawai’i Institute regarding Marine Biology I’m hoping this will help.

I’ve never ever raised all preferred aquarium kinds (such as blue- or red-legs), but We have raised several of the regional California species

It can correlate along with your findings: “There is certainly a lot of variability certainly various other hermit crabs within mating choices, but I shall attempt to make you some realistic generalizations. At the very least this new larvae was not too difficult to increase by comparison to the majority of inverts. That have one difference, most of the hermit crab types with which I’m common brood its larvae externally (but inside the cover) up until it finish the nauplius values (early stage larvae, just like a baby brine shrimp), this period can differ anywhere between on 1 and 12 months, according to varieties. The fresh new women following launch possibly zoea otherwise megalopae (merely appreciate terms to get more-and-elderly larval values) which usually feed on phyto- and you may zooplankton.
