I made this account to ask if anyone has bred Arrow Crabs before? We had brittle stars, fire worms, tube worms, bristle worms as hitchhikers in the live rock but now there is hundreds of tiny things running all over. The arrow crabs had babies twice and is pregnant again. The tadpoles were swimming on top and then vanished both times. Now I’m seeing all sorts of critters in different stages.
Arrow crab stages??

I can see the videos, but they come through as downloads. Another option is to upload them to YouTube and then share the YouTube link.
Thank you!

I don't know if any hobbyists have reared arrow crabs before, but it has been done in laboratory settings using Baby Brine Shrimp (Artemia nauplii):

Not baby arrow crabs, im not too sure if arrow crab larvae survives long in home aquaria, Ive had many spawn in our tanks and never seen any after the eggs disappear. In your videos those are amphipods aka scuds
I know it is rare to successfully breed Arrow Crabs and there is nothing I find only past the tadpole stage. Thank you for your help!

Yeah, they're pelagic larvae, so they wouldn't last long in most home aquaria (predation, equipment, etc. would all decrease their numbers). OP, if you're wanting to breed these guys, you'll need to pull the larvae out of the display tank into a rearing tank to protect them as they grow. (Keep us updated on how it goes if you try it - I love these sorts of things).
Here's a link to a public PDF of the full paper I linked above - the full paper goes into some more details both on keeping the female broodstock and on the rearing of the larvae: https://www.researchgate.net/public..._Brachyura_Inachidae_reared_in_the_laboratory
I kind of want to try it now haha. Any time!
That is so interesting! Our crab has continually been pregnantI don't know if any hobbyists have reared arrow crabs before, but it has been done in laboratory settings using Baby Brine Shrimp (Artemia nauplii):

since we got the male crab, the female was fertilized and had babies about two weeks later. That night she had them, her eggs returned and were again fertilized. She had another brood and is pregnant currently. I never thought it would be as reoccurring. Another video attached shows the varies sizes and kinds of life I’ve been seeing lately
Saltwater tank has so much life moving about
