    What would make my emerald crab turn orange? It was a healthy green when placed in the tank about ten or so months ago, but now definitely orange.

    All of a sudden my emerald crab is showing way too much interest in my corals. Not sure if he is eating them or picking stuff off them. This morning he had a death grip on my golden yellow polyp.....I recently introduced new corals and that seemed to be triggering the issue. Previously he...

    AHHHHH!! I JUST GOT MY PISTOL SHRIMP, IT MADE A BEAUTIFUL RELATIONSHIP WITH MY GOBY, MADE A NICE HOME FOR THE TWO OF THEM! AND THEN THE EMERALD CRAB COMES OVER AND COMPLETELY DESTROYED THEIR HOME! ATTACKED THE SHRIMP! I took it out. It was the only option. I had to put it in a bag and float it...

    Hey guys, I walked into my basement earlier today to take a look at my tank, and when I got down there I noticed that my Cinnamon Polyps were closed quite a bit. Right below them on a rock I saw an(at least what I think) emerald crab. Ive had them in the past with no issues, but know they can...

    Got a new mushroom a few weeks ago. He's (I've assigned him a gender) been doing great, opening up right away, easily tripled in size since we put him in. Then I noticed he didn't open yesterday. Kept an eye on him, thinking he may need to be moved in the tank. This morning he's just a...

    I have purchased emerald crabs and snails 3 different times and each time they die. I drip acclimate them for a really long time until the salt level are equal, but it seems that as soon as they hit the tank they die. I'll leave them in one spot in the tank and the day they will still be there...

    I used to hate emerald crabs after I caught them eating zoas in the reef. But I picked some up for my fish only tank a few days ago and am actually really enjoying them. I got two for a 34g tank. I'm going back to my LFS today and was wondering if there would be any issues with picking up...

    I really am completely stumped as to why these creatures are dying. It seems that every emerald crab, hermit crab, and snail I put into my tank dies. And they aren't being eaten as I find fully intact bodies. I normally would be quick to blame copper but my anemones are thriving (in fact there...

    Anyone know any tried and true methods of removing bubble algae from rocks? Preferably without adding emerald crabs into my tank. I got a lot of it and removing the rocks isn't an option.

    Over the last few weeks I have lost a mcCosker and an indigo dotty. I see the flame chase the said fish but never make contact. Then in the time of a night the fish is just bones. My other stock is some hermits, RBTA, two clowns, chromis, firefish. Perfect levels in my tank. I have notice my...

    Just curious, I had my most awesome fish die (my mandarin :( ) found several tiny hermit crabs eating away at what was left of him. Its hard for me to believe he died naturally since he was swimming around and hunting normally the previous night. This morning I found him dead. Any chance...
