-“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 these crabs are competitive I will however just take them right back into the shop and get one thing way more compatible having my tanks

Marine Hermit crab reproduction methods – 7/ Hello WWM Crew, I’m a long time reader and fan of the site.

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 big and more competitive and was principal during this “interaction”. Small way more inactive crab is just one We later watched introducing little larvae later in the day (I became radiant a flashlight with it). He has produced two moments currently. I can’t appear to find a response in the if they are dioecious or hermaphrodite within my guides (I’ve books from the Fenner, Delbeek and you may Sprung, Tullock, et al). I understand that isn’t from earth smashing characteristics, however, I found myself merely interested. Thank you ahead! I think You will find an answer for your but it’s based on Ca varieties (approximately pertains to warm types too). This is actually the answer Personally acquired today out-of an associate off exploit Dr. Robert Toonen Assistant Browse Teacher, College or university off Their state in the Manoa College from Water and Planet Science and you will Technology, The newest Hawai’i Institute out-of Marine Biology I’m hoping this helps.

I have never ever elevated all prominent aquarium kinds (such as for instance blue- or reddish-legs), but You will find raised several of the local California variety

It will correlate with your conclusions: “You will find quite a bit of variability among various other hermit crabs inside their mating conclusion, but I’ll just be sure to give you specific realistic generalizations. At the very least the fresh larvae was relatively easy to boost in comparison to the majority of inverts. Which have you to exception to this rule, all of the hermit crab varieties in which I am common brood their larvae on the outside (however, into the layer) up until it finish the nauplius amount (early stage larvae, like a child brine shrimp), this period sites de rencontres pour gratuit may vary between regarding 1 and one year, according to the kinds. The latest people up coming release sometimes zoea otherwise megalopae (only prefer terminology to get more-and-more mature larval amounts) and that usually feed on phyto- and zooplankton.
