View Full Version : Fiddler Crab tank

06-25-2010, 10:37 PM
As I type I'm working on a 10 gallon brackish tank for some fiddler crabs... been wanting to do something "different" from my normal community tanks and figured it was either this or an emperor scorpion... these sounded more fun lol

So as of a minute ago here's what I've got so far, plan to update as I go along :19:

Any advice or hints welcome! Battery is dead, so all I'm gonna do is play in the sand until it's charged again :hmm3grin2orange:

Just make sure they have some area where they can get out of the water as even though they're fully aquatic they need to get out sometimes. Oh, and best of luck! I'd like to make a Fiddler tank at some point myself!

I would make sure you have a very good fitting top, with no spaces to get out around filters or anything... they will get out given any opportunity lol.

Yeah, plan on having it a viv type tank, would've taken pics but the camera died on me...

Not running a filter or heater on the tank, my room averages 75 or more even in the winter due to all the tank, and for the lack of filter I'm just gonna do a water change every couple days... it's like a gallon of water :hmm3grin2orange:

DIY lid, using plexi glass from lowes and a hinge from your average AGA or Aqueon glass top

pics in a few

Oh ok lol.. I just remember finding my fiddler crab I had way back behind my entertainment center all dried up.. they'll take any opening they can find lol.

That looks really cool! Are you adding more water?

I don't think they put off much waste, but you may want to get a small sponge filter- they make 'small world' filters for like, goldfish bowls, that would go well in there and are driven my an air pump.

That's all the water I plan on, its about 2 inches deep at it's deepest, we sell them at the store I work in but I don't think they'll work in that little of water.

Any more water and the sand bank wouldn't work as well :ssmile:

Are you sure? I thought they weren't fully aquatic. The fact that they need land makes them not fully aquatic right?

Anyway, your tank looks great so far, and this will be a very good journal to follow!

:hmm3grin2orange: Emmanuel you are quite correct. Sorry, been one of those days. Reading it back over I clearly contradicted myself in that sentence

Got my crabs! Acclimating as I type this, taking pics as soon as they get out...

Thinking about it, I might add another inch or so of water to this setup, the crabs kinda look dull out of land but awesome in the water thumbs2:

I'll take a video tomorrow, after I feed them/during feeding time :)

Wow, those are some neat looking Fiddler Crabs. I have never seen any that look like that. The only ones I have seen were white/ light brown.

Very nice! The coloration on the crabs is just great thumbs2:

Thanks all! The coloring is what made me want them lol, watermelon crabs is what they came in as, they're from singapore.

Don't htink there's gonna be a video unless they get out of their burrows lol, they've each made a burrow just about side by side and I haven't seen them this morning... maybe I'll get a few more tomorrow :19:
