crab

Hi everyone I am in process of building my own clean up cre for my new 120 mixed, and curious if anyone has knowledge or has a cheat sheet of what each type of clean up crew invert is good at. Specifically the differences in hermits and how they can help for specific algae or what snails are...

Emerald crab, hanging out (cleaning) the zoa bases

Starting to make some progress on lighting and details I think. Advice and comments welcome!! Click to see full size photos.

I recently bought a Trapezia rufopunctata. From my research, their preferred coral seems to be Pocillopora - that's my assumption because all the photos of them in the wild are of them in Pocillopora. I currently only have a Pocillopora recovering from STN, but I do have a Stylophora mini colony...

The Name Schizoproida Why is this crab seemingly based on the mental disorder schizophrenia? I don't know much about schizophrenia, but it may have to do with the crab's habit of ripping off pieces of seaweed and sponges for decorations. They seem to have a compulsion to decorate themselves...

This carb has made a hole in the sand under all my rocks I would never be able to get him. Should I leave him in or get him out. Is he safe to leave in?

I am aware that some shipper ship certain hermit crabs with no water, just damp paper towels. I was wondering if the same would be okay for non-hermit crabs like decorator crabs, xanthid crabs, etc. I figured it would be okay since even blue crabs at fish markets live for a long time without any...

TubsBlue and RadioactiveDragonEyes Zoanthids and a PomPom Crab lurking too ;)

I'm unsure whether this might actually be a white stripped hermit because unlike the pictures I came across the bands on its legs are actually a brown colour and the shell is not as dark. However despite that the crab now lives in a 3i conch shell it does not bother anything else apart from the...

I'm currently a graduate student at UNC Charlotte working on a PhD in biology, concentrating in coastal and marine ecology. My lab does a significant amount of research on fiddler crabs and right now we are focusing on a project using the Atlantic sand fiddler crab, Leptuca pugilator. UNC...

I just purchased a Maxima Clam today and I have a Green Emerald Crab that is checking it out. Are these two combatable with each other? Or will I need to dispose of the crab?

OK. I'm looking to fine tune a Ricordea florida exhibit at work. Some of them look fine, but others are shrinking and I cannot put my finger on why. 60 gallon custom made glass tank made by TankMeUSA. 24"x24"x25" Kessil 360 W Tuna blue light about 8"over the top of the water. Light at about...

Hey guys so i noticed one of my hermits has something growing on his side inside his shell it usually hides but i got it to come this took some pictures i was thinking it’s some type of feather duster maybe? If so i kind want to keep it how to extract it lol or will it come out on its own

We have had this mystery crab in our tank for a while now and even with traps have not been able to get him out! Sneaky guy! He has molted so hopefully this will help. He is a little fuzzy but Im pretty sure its not a gorilla crab? One claw is very large compared to the other, he has red eyes...

Heyo, I got these awesome pompom/boxer crab. I wonder if it is a male or female crab - usually crabs have like a round or pointy shape on the belly but these seem kinda weird and I can't really tell. the shell pattern also seems to be different on them - idk if that is related to sex or just...

This crab was on a rock i purchased. What kind is he? Thanks! Sorry for bad pictures, my phone does not like the metal halide lighting.

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...
