crab

Ahoy, I would like to know the ID for this crab. Classic question -> good or bad? If other pictures are needed to ID it, let me know which parts of the crab are importatnt. It is sitting in the sump right now just to be sure. Thanks in advance! PS: I named it Karatecrab LOL

I've had this weird Emerald Crab for the longest time and he's not acting like an Emerald Crab he's acting like a Coral Crab! I moved him from his Coral on some Bubble Algae I want him to eat but instead of eating the Bubble Algae he walked right back to his Birdsnest?! When I try to frag my...

Hi I was thinking about buying a calico crab. I was wondering if anyone here has experience with these beauties. I just need to know what to feed them, temps, decor and the such. I would be keeping it in a species tank with a single specimen.

Hi, Just wanted to know which site/vendor gives the most for your money. Where is the best value on clean up crews out there? Thanks

I am not sure if i have a problem yet or not but I was watching my emerald crab really go to town on my birds nest last night. I watched him pinch at the coral a lot then move one, and later he came back! I used a plastic arm to push him away the second time. I am sure he came back later in the...

I saw a thread around here a few weeks ago that had pics of all different clean up crew critters and how they work in the aquarium. I tried searching for it but can’t find it. Anyone know where it might be hiding and can link it ?

@Lionfish Lair Found this little guy today. Can he be ID'd or is he just too small? Most of all, Safe? Can I keep him? Seahorse Tank safe?Bottom view Top ViewAnd one for good measure ;)

Hello, I have a relatively new tank and that has been up and running for about two full months now. In the tank I have two clowns, two Astrea snails, a rose bubble tip anemone, and an emerald crab. My anemones health seems to of gone up and down and up and down lately… One thing that I've...

any idea what this guy is? Just found him chillin on our oyster

While trying to move an emerald crab to a different tank, I tried to pushed him off the rock with forceps. In the process, I accidentally hit his claw pretty hard against the rock. When I finally got him moved, I looked closer and saw that his claw seems to be dislocated and he keeps grabbing at...

This little guy came in on a piece of coral. What is he? Good or bad? In the sump for now.

I've raised Land Hermit Crabs for a few years, and now I want to raise Marine Hermit Crabs. I have no intention to raise other animals in the aquarium, but should I? Would it hurt my Crabs if they're raised with only other Crabs of their species?

I have always been a fan of emerald crabs and have kept them for the past three years. Two of the ones I have now are the green variety and have grown fairly large. The body (not counting claws) is bigger than a quarter, close to a 50 cent piece. Yesterday while feeding my tank. I witnessed...

I found this crab a couple month back as probably 1/4 the size that it is right now( it's now about an inch). I first found it on a bubble coral and right now I just caught in on my Duncan coral. If anybody knows if this type of crab is harmful or if it's not a big deal please let me know thanks.

This guy has stripped the side of one of my Acros. He was in another one that did need help recovering and now it is. But, he moved over to this one that I thought was doing well. It is a fuzzy relish brown color with blue eyes. Thoughts?

bought a new 11 pound Fiji rock a couple days ago and am seeing a small snail and crab, probably more critters yet to be discovered. The snail is probably 1/16 of an inch across and the crab is about 1/8 of an inch across (very rough estimates). Please let me know if either of the guys are...
