-„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 the these types of crabs was competitive I will without a doubt just take her or him straight back with the store and possess things a lot more appropriate getting 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.

You to crab is significantly big and a lot more competitive and you may is actually principal in this „interaction”. The smaller so much more passive crab is just one I later on watched introducing lightweight larvae at night (I found myself shining a flashlight in it). He has spawned several minutes currently. I can’t seem to see a reply about if they are dioecious otherwise hermaphrodite in my own instructions (You will find guides of the Fenner, Delbeek and you may Sprung, Tullock, et al). I am aware it is not regarding planet shattering advantages, however, I found myself simply interested. Thank you in advance! I believe We have an account you but it’s based on Ca varieties (more or less pertains to exotic species as well). This is actually the address Personally, i obtained now regarding an associate out-of mine Dr. localmilfselfies-coupon Robert Toonen Assistant Search Professor, College or university of Their state within Manoa College or university of Water and you may Planet Research and Technology, The fresh new Hawai’i Institute of Aquatic Biology I hope this helps.

I’ve never raised some of the preferred tank varieties (particularly blue- or purple-legs), however, I have increased several of the local Ca variety

It will correlate together with your results: „There clearly was a large amount of variability certainly one of additional hermit crabs within their mating decisions, but I am going to just be sure to give you specific reasonable generalizations. At least the fresh new larvae are relatively simple to increase in comparison to many inverts. Which have that exclusion, all of the hermit crab species that I am common brood its larvae on the exterior (however, inside the cover) until they finish the nauplius values (early stage larvae, like an infant brine shrimp), this period may vary ranging from regarding the 1 and 12 months, according to types. The new females next release often zoea or megalopae (only like words to get more-and-more mature larval values) and that usually feed on phyto- and you will zooplankton.
