This type of crabs wear shells on the backs like the hermit crab, but the dogs shop named him or her “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 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 escort service Wichita Falls 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 such crabs is actually competitive I’m able to of course get her or him back with the store and now have anything even more appropriate to own my personal tanks

Marine Hermit crab reproduction methods – 7/ Hello WWM Crew, Paul Mansur here today> 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 big and more competitive and try principal in this “interaction”. The smaller more passive crab is just one I after noticed starting smaller larvae at night (I was glowing a torch inside it). He has produced a few minutes already. I am unable to frequently select an answer regarding if they’re dioecious or hermaphrodite in my own guides (I have instructions because of the Fenner, Delbeek and you may Sprung, Tullock, et al). I’m sure that isn’t from planet smashing advantages, however, I found myself merely curious. Thanks ahead! I do believe We have an account you but it is based on Ca varieties (about relates to exotic kinds too). This is actually the answer i gotten now out of an associate of mine Dr. Robert Toonen Assistant Look Teacher, College or university of Hawaii within Manoa University away from Ocean and you will World Research and you may Tech, The Hawai’i Institute regarding Aquatic Biology I really hope this helps.

You will find never elevated the common tank variety (instance blue- otherwise red-colored-legs), but You will find raised several of the regional California variety

It will associate together with your results: “You will find quite a bit of variability certainly one of other hermit crabs within their mating choices, but I am going to make an effort to make you some realistic generalizations. At the least the latest larvae is actually relatively easy to increase in contrast to the majority inverts. That have one to different, most of the hermit crab types that I’m common brood the larvae on the exterior (but within the layer) until it complete the nauplius degrees (early stage larvae, like a baby brine shrimp), this period may vary ranging from regarding the step 1 and one year, with regards to the varieties. Brand new women after that launch either zoea or megalopae (only appreciation words for lots more-and-more mature larval grade) and therefore generally speaking feed on phyto- and you may zooplankton.
