I just picked up an emerald crab for my 10g nano and I have so far one toadstool in there. After checking up on him, i noticed he was crawling on my toadstool that was previously opened and now all shrunken up. I also noticed a tiny chunk of my toadstool missing. I am so mad!! I love my little...

I have a timer on my light so it turns off before I come home from work, when I turned my room light on I saw a small crab with a red body with white spots and white legs, he’s probably only about a half inch across, any idea what it is?

Seems like some kind of mollusk that opens, any ideas? Check video something Black looks like tongue comes out

Hello would anyone be interested in buying a medium to large size emerald crab? Very healthy and fat just can't keep him pet store said reef safe but he has been bothering my anemone so I have to give him away. Would like $15 can do shipping but would prefer pickup or drop-off. In Texas any...

Hi all, just dipping an Acro colony and noticed this guy deep down in there, trying to get a ID, difficult to get a clear shot! Any sure answers? At first i thought it was a decorator crab but its too chunky.

Hey everyone, I got a hitchhiker today. Not sure if he's reef safe or not? He's tiny at the moment. Any help would be greatly appreciated. Thanks

Hi, I have a Fluval Evo that is starting to get some bubble algae, I'm wanting to try and control it by a natural method like an emerald crab but I'm unsure whether it would get along with the porcelain crab that I have hosting my RBTA. has anyone got any experience keeping the two or are they...

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.
