These types of crabs don shells on the backs like the hermit crab, nevertheless pet shop entitled 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

If this type woosa telefoonnummer of crabs is aggressive I’m able to of course need her or him right back with the store as well as have one thing much more suitable for my personal 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 big and a lot more competitive and you will try dominant in this “interaction”. The smaller a whole lot more couch potato crab is one We later on saw initiating small larvae in the evening (I became shining a flashlight on it). He’s produced two times already. I can not frequently pick a response from the if they are dioecious or hermaphrodite inside my books (You will find books because of the Fenner, Delbeek and you may Sprung, Tullock, mais aussi al). I know that isn’t out of planet shattering characteristics, but I became simply interested. Thanks beforehand! I think We have an account your however it is based on California varieties (more or less pertains to warm kinds as well). This is basically the respond to Personally acquired today off a part regarding exploit Dr. Robert Toonen Secretary Lookup Professor, College out of Their state during the Manoa School from Sea and World Science and you may Technology, The latest Hawai’i Institute out-of Marine Biology I really hope this helps.

We have never increased the prominent aquarium types (eg bluish- otherwise red-colored-legs), however, I have elevated many of the local Ca variety

It can associate together with your findings: “Discover a substantial amount of variability certainly additional hermit crabs within mating behavior, but I shall try to leave you specific practical generalizations. At the least this new larvae is actually not too difficult to boost in contrast to the majority inverts. With that different, all the hermit crab types with which I am familiar brood its larvae on the outside (however, during the cover) until it complete the nauplius grade (initial phase larvae, the same as an infant brine shrimp), this era can vary ranging from regarding step 1 and one year, according to variety. The fresh female up coming release both zoea or megalopae (merely love words to get more-and-older larval amount) hence normally prey on phyto- and you can zooplankton.
