These types of crabs don shells on their backs such as the hermit crab, nevertheless pet store 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

If these types of crabs was aggressive I can obviously get her or him back to your shop as well as have things so much more compatible to possess 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.

That crab is a lot larger and a lot more aggressive and try dominating with this “interaction”. Small a lot more inactive crab is certainly one I afterwards noticed establishing smaller larvae in the evening (I was radiant a torch with it). He’s spawned two minutes already. I can not apparently come across a reply from the if they are dioecious or hermaphrodite in my own courses (I’ve courses by Fenner, Delbeek and you will Sprung, Tullock, mais aussi al). I know that isn’t from earth shattering advantages, however, I became just interested. Thank you ahead! I think I have an account your but it is centered on California types (about pertains to exotic types too). This is actually the answer i gotten now regarding a member regarding mine Dr. Robert Toonen Assistant Search Professor, College out-of Their state on Manoa School away from Ocean and you may Earth Research and Tech, The fresh Hawai’i Institute from Marine Biology I am hoping it will help.

I have never ever raised some of the prominent tank species (like bluish- or red-colored-legs), but I’ve raised many of the regional California species

It can associate together with your results: “There is a substantial amount of variability certainly other hermit crabs inside their mating choices, but I shall just be sure to make you specific sensible generalizations. No less than new larvae are relatively simple to raise by comparison to the majority of inverts. Which have one exclusion, most of the hermit crab variety that I’m familiar brood the larvae externally (however, in shell) up until it complete the nauplius levels (initial phase larvae, similar to a baby brine shrimp), this era may vary anywhere between in the 1 and you can 12 months, depending on the variety. The people upcoming discharge often zoea or megalopae (only prefer terminology for lots more-and-elderly larval levels) and that normally prey on phyto- and you may zooplankton.
