crab

Have a little guy to sell, if anyone wants it within next few days

Hey everyone, need help identifying this crab, was sold to me as a emerald crab, I have some doubts. Emeralds crabs are pretty hard to find in Australia, soo thought I would take the chance and buy it, just seeing if anyone can confirm if its a emerald crab, or a pest crab. Thank you in advance

Tried to get a decent pic of it. It’s living under some GSP. Any help is appreciated thank you!

Hello .. I’m getting back to the hobby and resurrecting my 15 yrs old 70g tank. planning to add variety of crabs, a couple of fish, and star fish. However, some crabs need to breath air so any ideas how to set that up? I was thinking of leaving the tip if a rock out of the water. Any suggestions?

Hi guys, i havent seen my strawberry crab since i put him in my tank. Yesterday i found his shell. Do they change their shells or is it died?

I have recently bought this crab from my LPS and they labeled it as a Sand Sifting Crab, which it is but I was wondering if someone could ID it so I can do more research on its compatibility within my tank. They told me they believed it was reef safe with caution, but they also didn't have much...

Hi all, I noticed I have a tiny (1/2") all white and pale crab in my tank. Because of his color and size, I couldn't get a clear picture. I have no idea where did he come from (larvae stuck in my last purchase?). He doesn't seem to bother other CUC (he is smaller) neither my corals. He looks...

Hello, i have an unusual pet which is a Red Rock Crab (Cancer productus) and just aquatic crabs in general are very hard to find good information about other than cooking. I've had him for about 9 months now. I keep the water temperature and salinity matched to his natural home (Puget Sound)...

I'm new and inexperienced, and I want to get a pet crab or crustacean. I was wondering what would be a good starter, like shrimp or crabs. Thanks for any help!

I look at my aquarium every night with a flashlight to see all the nocturnal critters out and about. I mainly see a bunch of crabs and snails but isopods and weird worms pop out every now and again. Earlier this week I saw a “cloud” of some invertebrate larvae, I was hoping they were porcelain...

Just curious if anyone knows the proper identification of this crab? The guy at the store said it came in on some rock in an NPS coral shipment. He ate one of my tube anemones unfortunately so I put him in this breeding box for now Thanks!

I have a new 25 gallon to wich im transferring two clownfish, tailspot blenny and blood shrimp. I don’t want to add any more fish and instead want to focus on inverts, I love them, crabs, sea stars, urchins, you name it. What is a good list of good inverts I can add that aren’t super tiny...

First time posting, I hope this is the correct sub forum. I found this little hitchhiker hiding in my GSP rock. Today it was snacking on my hammer so definitely not friendly. Can anyone ID it, please? It's not a gorilla crab, and someone on Reddit said it's a Calico crab. I'm in Southeast...

At first glance, the Red Round Crab has the appearance of being cooked to delicious perfection. Furthermore, it also goes by a similarly tasty sounding monikers “Strawberry Crab” and “Red Stone Crab.” The bright rosy red is a telltale sign your crustacean is ready to eat. However, in this...

Anyone know why pom pom crabs are so notoriously difficult to rear? Google shows a couple of dedicated reefers who have tried with all kinds of complicated equipment. Apparently breeding them is about as easy as it is for any invert, but once the young hatch, it suddenly gets too difficult to...

I recently posted about a concerning decline in my reef tank corals with seemingly no cause. My parameters have always been good and stable for the most part. I was very confused because an entire colony of 12+ rasta zoanthids and a smaller frag with 3 polyps disappeared overnight, but that was...

Found hiding in a coral

Nearly Free to Good Home (1$): a couple Red Mithrax Crabs, whatever few snails I can capture (turbo and assorted others). One sea urchin, Pasadena, CA 91105. Pick up only. Text me: 310-560-3656 or DM via this forum. My tank no longer needs bulldozers in the clean up crew. Note, these crabs have...

Gorilla crab up for grabs in Chadds Ford, PA 19317, near Longwood Gardens. It's about the size of a Ping-Pong ball. It's terrorizing my sump inhabitants and I would like it gone. PM if interested.

Hi I found a snail size crab shell or dead crad in my tank. Its white and semi transparent so i think its the shell? I have no idea where it came from and if its an empty shell, should I be worried? A bit more details I have started my tank in march with new dry sand, and new marco rock. I...

Sorry for photo quality, the tank's on the ground at a weird angle. I can try for more pics if needed. This is Pilumnus sayi, the Spineback Hairy Crab. I found him at about half an inch across in March, on some live rock, and he's now a good 2-3" across. He'll hit about an inch across in the...

Just though this was cool, recently got some female emerald crabs from reef cleaners in hopes of tackling a moderate BA outbreak (even though nitro is undetectable) , they have completely ignored the Bubble Algae … One of the emerald crabs kept going to an area in the rocks and eating some sort...

I was able to catch a gorilla crab that came along as a hitchhiker on the some live rock I added to the tank. If anyone would like it for their sump or any other reason, let me know. It’s free. I’m located in southern York County, PA and could meet in the York, PA or Baltimore, MD areas.
