This type of crabs wear shells on the backs such as the hermit crab, although dogs shop entitled them “hairy 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 sugar daddy Bloomington IN 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 try competitive I could without a doubt simply take her or him back on the store and also some thing far more suitable for 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.

That crab is much huge and more aggressive and you can try dominating during this “interaction”. Small far more inactive crab is one We later on noticed releasing small larvae later in the day (I found myself radiant a torch inside). He’s got spawned a couple minutes currently. I can not apparently see a reply regarding if they are dioecious otherwise hermaphrodite during my books (I’ve books by the Fenner, Delbeek and you can Sprung, Tullock, mais aussi al). I’m sure this isn’t regarding environment smashing pros, but I found myself simply interested. Thanks a lot ahead of time! I believe I have an account you however it is considering California kinds (about pertains to tropical varieties as well). This is basically the address I personally obtained now regarding a part of mine Dr. Robert Toonen Secretary Search Teacher, College out of The state within Manoa College or university out of Ocean and you can Environment Research and Technical, The newest Hawai’i Institute off Aquatic Biology I’m hoping this helps.

I have never elevated the popular aquarium kinds (such as for example bluish- or reddish-legs), but I have elevated a number of the local California types

It will associate along with your conclusions: “You will find a lot of variability one of more hermit crabs in their mating decisions, but I shall make an effort to give you some realistic generalizations. About new larvae are relatively simple to raise by comparison to the majority of inverts. Having that exemption, all the hermit crab varieties that I am common brood their larvae externally (however, inside cover) up to it complete the nauplius grade (early stage larvae, just like a baby brine shrimp), this era can differ ranging from throughout the step 1 and you can 1 year, with respect to the varieties. The new people then discharge possibly zoea otherwise megalopae (just prefer terminology for lots more-and-old larval grade) which generally speaking prey on phyto- and you may zooplankton.
