These types of crabs wear shells on their backs including the hermit crab, but the pets shop named her or him “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 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 these types of crabs are aggressive I could of course take her or him straight back for the store and have something much more appropriate 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 consejos para citas en una 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 much large plus aggressive and you will are principal with this “interaction”. Small way more couch potato crab is certainly one I after noticed releasing smaller larvae later in the day (I found myself radiant a torch with it). They have spawned one or two minutes currently. I am unable to apparently select a reply on when they dioecious or hermaphrodite inside my courses (I’ve guides because of the Fenner, Delbeek and Sprung, Tullock, ainsi que al). I’m sure this isn’t of planet smashing characteristics, however, I found myself simply interested. Thank-you beforehand! I believe I’ve an answer for your however it is predicated on California species (about applies to warm kinds also). Here is the address I personally gotten now of an associate off exploit Dr. Robert Toonen Assistant Lookup Professor, School out of Hawaii during the Manoa University out of Sea and Environment Technology and you can Technical, The newest Hawai’i Institute off Marine Biology I’m hoping this will help to.

We have never ever increased all common aquarium varieties (such as blue- or yellow-legs), however, I have elevated many of the regional California varieties

It can correlate together with your findings: “There is quite a bit of variability certainly some other hermit crabs in their mating conclusion, but I will you will need to leave you specific sensible generalizations. At the least the fresh new larvae are relatively simple to boost in contrast to the majority of inverts. Which have one difference, most of the hermit crab types in which I’m common brood its larvae externally (however, in layer) up until it finish the nauplius amounts (initial phase larvae, similar to a baby brine shrimp), this era can vary anywhere between regarding 1 and 1 year, according to variety. The fresh new women after that launch sometimes zoea or megalopae (simply adore words to get more-and-elderly larval level) hence typically feast upon phyto- and you will zooplankton.
