-“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

When the these crabs is competitive I could obviously take them right back to your store and now have something even more compatible having my personal tanks

Marine Hermit crab reproduction methods – match-promotiecodes 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 crab is a lot big and much more competitive and you may is dominant with this “interaction”. Small a whole lot more inactive crab is but one I after spotted starting small larvae in the evening (I became glowing a flashlight involved). They have spawned a couple of minutes currently. I can not appear to come across an answer regarding the if they’re dioecious or hermaphrodite inside my courses (We have books of the Fenner, Delbeek and Sprung, Tullock, et al). I’m sure this is simply not away from planet shattering characteristics, however, I became simply interested. Thank-you in advance! I do believe I have an account your however it is centered on Ca varieties (roughly pertains to exotic species as well). This is basically the answer I know obtained today regarding a member of exploit Dr. Robert Toonen Secretary Search Professor, University away from Hawaii from the Manoa College off Ocean and you may Earth Research and you can Technology, The newest Hawai’i Institute regarding Aquatic Biology I hope this will help to.

I’ve never increased any of the preferred aquarium kinds (for example blue- otherwise red-colored-legs), but We have increased several of the local California variety

It will associate along with your conclusions: “There can be a large amount of variability certainly one of different hermit crabs in their mating decisions, however, I shall try to leave you certain sensible generalizations. No less than new larvae is actually relatively easy to raise by comparison to many inverts. That have you to difference, most of the hermit crab variety that I’m familiar brood the larvae on the outside (but within the shell) until they complete the nauplius degree (initial phase larvae, just like a baby brine shrimp), this period may differ anywhere between on step 1 and one year, depending on the species. This new women upcoming release both zoea otherwise megalopae (simply really love terms and conditions for much more-and-older larval levels) hence typically prey on phyto- and you can zooplankton.
