When fiddler crabs molt they will eat very little and will stay upside down for many hours, DO NOT touch or mess with your fiddler crab when its molting! Fiddler crabs may look hard but are acutally VERY FRAGILE!
I once accidentally KILLED one of my females when I tried to help it back up...
After your fiddler crab is done molting you may see him eating the old shell THATS OK,fiddler crabs will eat the old shell for nutrition,DONT TAKE OUT THE SHELL EVEN IF THERE ARE NO CRABS AROUND IT! Your crab needs the nutrition and will only it the shell when no ones around (exception for other crabs)
Be sure to isolate your fiddler crab when hes done molting,after he starts to be active and his new shell comes in you can put him back in the main tank...

Most of this is untrue I have two female fiddlers for a month now. They are in a fish tank with many fish totally immersed in water and doing great !!!
That's one month, wait for more.
<p>Maybe do a spell check before you point out how uneducated people are..</p>
Employees at Pet Co. do not go to school to tell you how to take care of your animals. They are in educated. I have learned the same thing.
<p>I would like to know if I could keep them on gravel... Because mine are living in it right know</p>
I would like to know if I should feed and change my fiddler crabs water when they hibernate
I just bought a fiddler crab, but I wasn't told I needed a heater or salt water. Can I just use tap water for a certain amount of time til I get salt water?
<p>NO. First you'll have to make sure the tap water has been treated to remove any chloramines your city adds to the water. These will not evaporate just leaving buckets out overnight. If you don't treat tap water whatever you have will die.</p><p>I don't have crabs but I have goldfish. The same general rules apply to all. </p><p>Their health is dependent on the quality of their environment. I have never had any fish die of a disease because I make sure my water quality is very high and my fish has plenty of room. </p><p>If you want your crab to be healthy, make sure his environment is the best you can make it from the very start. If you already bought the crab, that means you need to go back and get whatever you need to supply him with his optimal environment now, not when you get around to it. </p>

Stupid ive had my fidler crab for a year and i have her in a tank full of water she loves it and they eat algae tablets not freekin betta food that floats un reachable
<p>I recently bought a better fish and a half gallon tank. Immediately after putting him in, I felt guilty and put him in a drink dispenser (approximately 3 gallon) until I could research more. He is now in a 10 gallon take with a place. I kept him in a large net to let him get used to the new guy and make sure he wasn't flaring. Later that night I took him out of the net and let him out into the new tank. He has gotten along great with the pleco so far. My husband and I were talking about getting a freshwater crab to go in. I originally thought a fiddler crab since Walmart keeps them in the same aquarium as a pleco. Just like everyone else, I was misled. But what can you do. So now I'm glad the last Walmart was out and I didn't bring any home. Are there any other crabs that would thrive in a freshwater tank with a betta and a place?</p>
<p>most crabs are actually brackish water, and won't enjoy living in fresh water. crayfish, sold as mini lobsters in some places, are a better choice and quite entertaining.</p>
I just bought mine at Walmart yesterday out of impulse. I saw that they were in a tank of water and thought that's how I take care of them not knowing the proper way. This was very helpful thank you
<p>just wanted to say Thank you. I picked up a few fiddlers for my classroom. Your information has been very helpful</p>
Just for future reference- dying** not dieing. Spell check is your friend when you're attempting to be an athority on a subject.
Just for future reference- authority** not athority. Looks like you should make friends with spell check too, especially when correcting someone else's spelling. ;)
<p>+1 my fried</p>
Your comment is totally priceless. Isn't it ironic?
I recommend using the spell checker yourself! :)
Depending on where you come from, it can be dieing and spell check does not find that spelling to be erroneous. Dying means to dye something a colour or to leave life. Dieing on the other hand, can mean to leave life or to cut with a die cutter depending on what you prefer. English is a great language of confusion and we are all better off if we do not correct others on the finer points until we ourselves know all the finer points.
<p>I have just bought 2 fiddler crabs from Walmart (Both female) and I had asked one of the workers what you need. I bought rocks and a 1.5 gallon aquarium kit. I had no clue you need a heater and stuff. She only told me to get betta pellets for food and some rocks. She completely did not know what she was talking about and I am very frustrated. Would you think they could survive in 1.5 gallon aquarium kit?</p>
<p>they were working at Walmart, what did you expect? They get paid minimum wage in a soul destroying job that robs them of their dignity. </p>
<p>i just bought two fiddler crabs from walmart and now they are sick, won't move and one lost one leg. i think its because i used gravel. thanks for this instructable really helped. will now make a lot of changes!</p>
I bought a couple at walmart, and i think these crabs are sooo adorable. Walmart doesn't even know how to take care of them. I make a little beach with some brackish water for them. They are great climbers, and they can grip on anything including glues that are used to make the fish tank and will climb out if there is an opened gap. I feed my crabs with betta pellets, plankton, and shrimp pellets.
<p>I've had some crabs for a few months in a 5gal aquarium with goldfish and snails. The water is low saline content, and I give the crabs &quot;salad shrimp&quot; occasionally, as well as white &quot;tums&quot; for calcium. They love the tablets and the male crab will sometimes sit on one to hoard it till he's done eating. The snail likes it, too. <br>The crabs have a plastic castle to climb on to get out of the water. I'm looking at your page to think of a new tank (bigger box) so the crabs get more sand area. Thanks. </p>
<p>Hello, need a little help. I am one of those people that did not get good info from the pet store. We got a red crab yesterday and he has already lost 2 legs in a fight with a catfish. I put him in a temporary home and he seems to be doing ok. Should I put time and $$ into a suitable home or will he not survive? Thank you </p>
<p>As an employee at Walmart, don't blame all of us for poor care.<br>My Walmart actual takes good care of the fish, got my Gustavo and my baby fiddlers yesterday, all healthy and high active. I have just two fiddlers so I got a single gallon tank until they get larger. I was going to get fine gravel today, but I may get sand instead, but the man told me that I should get an ornament for them to climb on and so they can bask and not to keep them underwater all the time. He actually takes the fiddlers out 2-3 times a day. He like to bring food for them too, maybe some freeze dried bloodworms like my betta loves. but im excited for my babies</p>
<p>my son received a fiddler crab and a red clawed crab for Christmas. We have them in a 5 gal tank, set up as you have recommended. We do not have a heater but do have a basking lamp on most of the day. The crabs do not seem to be eating anything. We put crab pellets in a plastic upside down lid, tried a few little pieces of cucumber and part of an algae tablet. All of it just sits there until we take it out. It's now been 4 days. They seem inactive and spend most of the time hiding. What do you recommend?</p>
I think my fiddler crab is dead hes been like that for a day plz help
<p>If our crab could talk he would most definitely thank you! We bought it from walmart and set it up as they had him in store. </p><p>A week later it was upside down. we presumed dead. Laid there all day until my hubby got him out to get rid of him and noticed he seemed to be moving slightly. We researched (as we should have done right away) and came across your instructions, which we followed. 3 months later he is healthy and active and we are about to get him a couple of friends. So thanks :)</p>
Thanks for this info. I have been looking and looking and came across your post. We live in Pensacola FL caught some fiddlers actually about a dozen so I actually should return some to the shore. They just seemed so funny and thought the more the merrier LOL. Anyway i pray I can keep the little fellas alive. I brought home some of the water from the shore I was wondering if I can just keep changing out the water from the same shore instead of commercial salts ?
This isn't a bad way to do it but if you want fish in the same tank they wouldn't have much room. <br> <br>I really recommend Underwater Islands they have these really cool products that make it so you can have crabs in your tank but not have to have your tank only half filled. <br> <br>I attached a picture from their website so everyone can check them out if you want. <br> <br>their website is www.underwaterislands.com <br> <br>Check it out and let me know what you think!
Wups that didn't work, I thought I had attached a picture.... let me try again.
In your instructions you mention &quot;there's a basket under here to hold up the sand, and the heaters under there&quot;. <br>please advise what type of basket you use. <br> Also another question, when fiddlers molt, (&quot;they will stay upside down for hours&quot;) are they ever upside down underwater for hours? I assumed mine was dead- maybe he was molting? thanks so much for all the info!
You are a Jack!@# for trying to correct someone's spelling in an info page...Get a Life!!! This for help with Fiddler Crabs and show how to make them happy not a grammar check convention!!! I am here because I bought crabs from Pet Supermarket. and they are dying also!
You can have a way smaller tank about about a quarter gallon
I found this Ible VERY useful when i began thinking about owning some red clawed crab... I have a Facebook page thats sort of part blog on my journey into owning crab, if you have crab, or are looking to get some, feel free to join my page <a href="http://www.facebook.com/redcrabdiaries" rel="nofollow">http://www.facebook.com/redcrabdiaries</a>
Lol my friend got a fiddler crab for her birthday from a friend and she had NO IDEA how to take care of one. She put it in a full fishbowl with sand, and then with further online research, she found out it was slowly dying in there, so she drained it to just a little water and a rock. She hates that thing like the plague and is her least favorite present. Poor girl.. <br> <br>At least her friend didn't get her more than one or else stating it would be awkward..
Also why is it tagged under tacos? <br>
I'm very glad this little bit on crabs was posted. I just rescued my fiddler crab from the wrath of Walmart. Apparently they don't feed the crabs because they do not sell what these crabs need to eat and they also keep the poor creatures confined in small plastic dishes with pebbles and a small amount of water in the bottom. Tomorrow i'm going to get the tank and all the recommended accessories and chlorine removers/aquarium salt. Once this little fella (i named him Bob) gets settled, i'll go back and save the others. That's a real nice example tank in the picture here and i hope to set mine up similar to it. For future reference to anyone who has ever considered purchasing an aquatic animal at Walmart, it probably hasn't eaten, slept, or had adequate housing for quite some time so don't be broken hearted if the poor dear dies the day after you bring it home. I saved a dwarf aquatic frog from there once (it was in the same kind of small plastic dish as the crab), gave it a nice large bowl and some food but he/she died the next day. Most of these stores do not feed these animals because they don't know what they eat and apparently they don't know how to keep them housed either. So yeah, just thought i'd throw that out there.
I've also seen tons of dead fish at the Walmart. Absolutely pathetic inhumane care they give to their animals. I'm not sure purchasing the poor creatures is the best route, however...as Walmart will simply respond by restocking them with more helpless creatures and being satisfied that their &quot;products&quot; are being sold. Maybe filing complaints with your local humane society or other authority would be more productive in getting Walmart to change its practices.
Indeed, walmart is terrible and i know that they will restock if i purchase the animals however those animals deserve some kind of a life away from the store shelf and it's against my very being to leave them there to die. Sadly, our local humane society is worthless. They do not do rescues or work for the &quot;lesser&quot; creatures such as fish and invertebrates. It's difficult to even get a horse/dog/cat abuser prosecuted here. I live in a very &quot;conservative&quot; town where animals take a back seat to guns, &quot;god&quot; and human enjoyment. The dogs and cats from our pounds are still sent to animal research facilities because the city council voted to let it continue even though many, including i, protested the decision. Every spring and autumn there is a deer cull (they hire snipers to come in and take out roughly 80 deer, which include fawns, adult males and adult females) in our two wooded/marshland parks because people complained of deer in their gardens. Illegal hunting is overlooked as well. This is the expected extreme behaviour of my town, which is sadly considered the &quot;birthplace of the republican party&quot; and one of Ted Nugent's home towns. Jackson, MI is not a nice place to live for animals or those that care about animals. If i could get national attention for the atrocities of this town i would gladly do so. But the problem is, who will listen and who will not be bribed or bought off? <br> <br>In the end though, i'm glad i saved the fiddler crabs from the walmart. They do restock them after the others die on the shelves. A couple weeks ago i noticed they were carrying purple clawed fiddlers. Such beautiful little creatures. Perhaps i could, maybe, just maybe get through to the pet department manager to post how to properly care for the fiddlers so that at least when people buy them, they know how to care for them.
how much sea salt do I add to a 1 gallon tank and one fiddler crab<br>
What ratio should the brackish water be?
Depending on how big your tank is brackish water is just a fancy word for salt water so for a 5 gal i would put in half a teaspoon heres a website for you http://aqualandpetsplus.com/Bug,%20Fiddler%20Crabs.htm
(I couldn't start a new comment so I decided to just reply.) I was wondering about your internal filter. I don't currently have a filter for my fiddlers, can you share the name or brand of yours? Also, is it a cordless filter? i'm curious. And where did you find those tunnels? I would prefer to get something more natural looking to camoflauge with my tank, but at this point I haven't found anything yet. Thanks in advance
