These crabs wear shells on their backs like the hermit crab, but the pets shop titled them “furry crabs”

I think I’ve an account your but it’s centered on Ca types (more or less pertains to tropical variety too)

-“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 know this is simply not off earth shattering benefits, but I found myself merely 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.

One to crab is a lot huge and more aggressive and is prominent during this “interaction”. The smaller a great deal more passive crab is certainly one We afterwards saw unveiling lightweight larvae later in the day (I happened to be glowing a flashlight inside). They have spawned a couple times already. I am unable to frequently come across a response throughout the if they are dioecious otherwise hermaphrodite during my instructions (We have courses by Fenner, Delbeek and you may Sprung, Tullock, ainsi que al). Thank you so much ahead of time! Here is the answer i acquired now out-of a part off exploit Dr. Robert Toonen Assistant Search Professor, College out of Hawaii within Manoa College or university out of Ocean and you will Environment Technology and you can Technical, Brand new Hawai’i Institute away from Marine Biology I am hoping it will help.

It does correlate together with your findings: “There can be quite a bit of variability certainly additional hermit crabs within their mating conclusion, but I shall you will need to leave you certain sensible generalizations. No less than the brand new larvae are not too difficult to raise by comparison to the majority of inverts. We have never increased any of the popular aquarium kinds (such as bluish- or purple-legs), but I’ve raised a number of the regional Ca variety. With one different, all hermit crab kinds with which I’m common brood their larvae on the exterior (however, into the cover) until it finish the nauplius amount (early stage larvae, just like a child brine shrimp), this era may vary ranging from regarding step 1 and you will 1 year, with regards to the kinds. The fresh new females upcoming launch often zoea otherwise megalopae (merely adore terms for much more-and-old larval amount) and that normally feed on phyto- and zooplankton.
