These types of crabs don shells on the backs such as the hermit crab, nevertheless animals store called him or her ”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 largefriends mobiel 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

If the these types of crabs is aggressive I will without a doubt simply take her or him right back with the store and also one thing even more appropriate getting my personal 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 definitely crab is much huge and much more competitive and you may is prominent in this ”interaction”. Small a lot more couch potato crab is the one I afterwards saw releasing tiny larvae in the evening (I happened to be radiant a flashlight with it). He’s spawned a couple times currently. I can’t frequently find a response on if they are dioecious otherwise hermaphrodite during my instructions (I’ve guides by the Fenner, Delbeek and you can Sprung, Tullock, et al). I am aware it is not of earth shattering pros, but I found myself only curious. Thank you so much in advance! In my opinion You will find an account you however it is predicated on Ca species (more or less relates to warm species also). Here is the answer I know gotten now of a part off mine Dr. Robert Toonen Assistant Research Teacher, College off Hawaii in the Manoa College out of Ocean and you may World Technology and Technology, The fresh Hawai’i Institute away from Marine Biology I hope it will help.

I’ve never ever elevated some of the preferred tank varieties (like blue- otherwise reddish-legs), but We have elevated a number of the local Ca variety

It does correlate along with your conclusions: ”There can be a large amount of variability certainly one of other hermit crabs inside their mating choices, but I will just be sure to leave you some reasonable generalizations. At least new larvae are relatively easy to boost in contrast to the majority of inverts. With one exemption, every hermit crab kinds in which I’m common brood the larvae externally (but when you look at the shell) up until they finish the nauplius stages (early stage larvae, exactly like an infant brine shrimp), this era may vary anywhere between regarding step 1 and you can one year, with respect to the varieties. The brand new girls up coming release possibly zoea or megalopae (just enjoy terminology for much more-and-older larval degree) and therefore typically feast upon phyto- and you will zooplankton.
