I believe I’ve an account your however it is considering California species (more or less relates to exotic varieties as well)

-“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. If these crabs are aggressive I will definitely take them back to the store and get something more compatible for my tanks. 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

I am aware it is not regarding planet shattering benefits, but I found myself only interested

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 definitely crab is much huge plus aggressive and you can are principal with this “interaction”. Small way more passive crab is just one I after spotted unveiling little larvae at night (I found myself glowing a flashlight involved). He has got produced a few times currently. I can’t appear to come across a reply regarding when they dioecious or hermaphrodite inside my books (We have instructions by the Fenner, Delbeek and you will Sprung, Tullock, et al). Thank you so much ahead of time! This is the respond to I personally gotten today from a part of mine Dr. Robert Toonen Secretary Search Professor, School off The state during the Manoa School out of Ocean and you will World Research and you will Technology, The new Hawai’i Institute from Aquatic Biology I am hoping it will help.

It does correlate with your findings: “There was a lot of variability one of additional hermit crabs in their mating behavior, but I’ll you will need to make you particular reasonable generalizations. At least brand new larvae are relatively simple to increase in comparison to most inverts. You will find never raised the common aquarium varieties (like bluish- or red-colored-legs), however, I have elevated several of the local Ca species. Which have you to definitely exclusion, all hermit crab species that I’m familiar brood its larvae externally (however, into the shell) until they finish the nauplius degrees (initial phase larvae, the same as an infant brine shrimp), this era may vary ranging from regarding 1 and you can 1 year, with regards to the varieties. This new jak dziaÅ‚a little armenia ladies next launch both zoea otherwise megalopae (just love conditions for more-and-earlier larval levels) which usually feast upon phyto- and you can zooplankton.
