Such crabs don shells to their backs like the hermit crab, nevertheless pet store named 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 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 such crabs is actually aggressive I’m able to without a doubt grab them back towards shop and just have something a great deal more appropriate 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 significantly large plus competitive and you can was prominent in this “interaction”. The smaller so much more inactive crab is the one I afterwards spotted initiating small larvae in the evening (I became glowing a torch on it). He has spawned one or two times currently. I can not appear to come across a response regarding when they dioecious or hermaphrodite in my courses (You will find books by the Fenner, Delbeek and you will Sprung, Tullock, et al). I’m sure that isn’t off earth smashing advantages, however, I was just interested. Thank-you ahead of time! In my opinion You will find an account you but it’s centered on Ca species (around applies to warm kinds too). This is the address Personally, i obtained today regarding a part out of mine Dr. Robert Toonen Assistant Lookup Professor, College or university regarding Their state during the Manoa College from Water and you will Environment Research and you may Tech, This new Hawai’i Institute away from Aquatic Biology I really hope this helps.

We have never ever increased any of the popular tank species (such as for instance blue- or purple-legs), however, We have raised a number of the local Ca varieties

It can correlate together with hoe iemand een bericht te sturen op whatsyourprice your results: “There clearly was a lot of variability certainly one of additional hermit crabs in their mating choices, however, I’ll you will need to leave you specific reasonable generalizations. At the very least the brand new larvae try relatively simple to raise by comparison to most inverts. Having that difference, the hermit crab varieties with which I’m familiar brood their larvae externally (however, in shell) until it complete the nauplius amount (initial phase larvae, similar to an infant brine shrimp), this era can differ between on step one and you may one year, according to variety. The new girls next launch either zoea otherwise megalopae (simply appreciation conditions for lots more-and-earlier larval amount) hence generally speaking prey on phyto- and you may zooplankton.
