emerald crab

My emerald crab is scraping at a shadowed part of my rockwork that has zero algae on it (and there is plenty of algae for her, she's doing a great job on it). Theres a little pile of rubble gathering under her and lots of it out in the water column. I don't even have a good hypothesis for what...

So I usually run a little bit if phyto before bed and this time I had quite the surprise! My emerald crabs appeared to have spawned a new generation of bubble destroyers. I was so surprised I couldn’t really “set up” a nice recording session- but I still managed to get a couple of places they...

Hi everyone, I have like 3 emerald crabs, and I noticed only one of them have this like algae or hairy stuff growing on its back. Does anyone know what is that? should I be concerned? should I remove him? On that note, would they eat seaweed? i’m concerned that they don’t have enough food and...

I recently cycled my tank and I entered the ugly stage so I got some clean up crew. My LFS recommended some emerald crabs along with a handful of other things. After I took them home and put them in the tank, I did some research because I thought that I’ve heard emerald crabs aren’t reef safe. I...

Emerald crab? I purchased 4 small emerald crabs months back, and just came across this big boy in my tank. I was in shock at his size already. But not really sure what type of crab he is or if he’s reef safe. Any help is appreciated. Thank you

I am having some bubble algae in my tank and I am looking for a way to manage it without any chemicals. I don't know much about pitho crabs but some people say they eat all algae and only sometimes pick at zoas. Emeralds I have heard can be hit and miss with the bubble algae and can sometimes...

Hi so recently we got an emerald crab that’s a little bit bigger in size… I would say he’s maybe 1” across? Definitely bigger. The BTA I have has been hosting my clown for awhile and suddenly have been noticing that the emerald crab specifically is hanging right by the BTA and almost picking at...

Howdy Y’all, I have for a long time been highly interested in starting a reef tank. As luck would have it while on a work trip to Barbados I entered a raffle and won the 2nd place prize which was a Waterbox 25 peninsula with a bunch of other goodies. Skip to month 3 and it has been going well so...

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...

Any ideas what this is. It doesn’t move and I can’t scrape it off. Just got him from the store

Ok. I need your opinion on this because my family is totally confused on this one. Back in February, we had a lively emerald crab named Jake. He was pretty large fella and would actively walk around at night in my 36 gallon reef tank. I also had a red brittle star and for a long time they were...

Do emerald crab nip at torches are night? I took some pictures. I thought they were reef safe? Anybody have this issue before?

Got an emerald crab from a LFS yesterday and just noticed little "bugs" crawling on him. What are these things? See video

Hey everyone, my aquarium has been very healthy and happy for some time and shows consistent improvement... For everyone but my Emerald Crabs. They don't ever seem to shed, have been dropping limbs, and their shells no longer appear bright and green. They are some of my longest cared for reef...

Bubble algae issue is getting way out of hand, I’ve got 6 emerald crabs in a 50 g display (90g system) and they haven’t made a dent. Manual removal isn’t really an option most of the rock work is covered in coral or fused together with putty making it way too large to pull out. I try to scrape...

So I have a pretty decent sized pistol shrimp paired up with a goby and all has been good...other than knowing exactly where they burrow cause of the pile of sand that hides them lol. But I got an emerald crab along with a few other additions today. Just an hr after adding them I found the...

Tonight as I was walking to my desk I noticed my clown going crazy and a bunch of white things floating in my tank. I finally found the culprit, an emerald crab releasing her eggs into the water column. I was able to get a short video of it, unfortunately after most of the eggs had been...

I added an emerald crab (along with a turbo snail who is an expert level hider) 2 days ago to my tank. The crab immediately went under a rock and stayed there for a couple days. Last night after lights out I went back and checked In the hole and it was still there and moving within the hole...

I have had an emerald crab in my tank for almost 3 months now. He is generally a good tank mate, and has good personality. He does great on the algae on my rocks, and even solved a Bryopsis outbreak I had. The problem…he is molting about one a month, and is approximately 2-3 times larger than...

Hey guys so I recently purchased a wrasse as well as a new CUC I brought Scarlett hermit crabs, a cleaner shrimp, blue leg hermit crabs, and a couple snails. Now I have a emeral crab from my last clean up crew and the emerald, cleaner shrimp and blood fire shrimp all hang out on and in the...

I haven my year old 40 breeder all sps reef tank an emerald crab (or so I thought). My corals have all been doing very well for the first 11 months. This past month I’ve noticed the slow death of 2 very nice corals, 1 being a bubble gum digi and the other being some no name acro. I came home...

Hi all, I got this from the local fish shop they said it was an emerald crab but red and it happens some times. Just thought I would post some pictures for opinions? The shop have a very good reputation so hoping they are right.

I have been wanting a Decorator Crab for the longest time, but I had a hitchhiker emerald crab on a rock I bought. Would it be safe to mix the 2 or will they fight eachother?
