so im gonna ask questions, post updates, and post occasional pics. i have a couple questions to start.
1.how many fiddlers should i add at once? my final stock will be 1 male 3 females
2.should i do sand sloping up or rocks sticking out of the water?
3. can i use a rock cave for lizards in the tank? so they can hide and get out of the water.
thats it for now:)

1.how many fiddlers should i add at once? my final stock will be 1 male 3 females all at once is fine
2.should i do sand sloping up or rocks sticking out of the water? sounds good
3. can i use a rock cave for lizards in the tank? so they can hide and get out of the water. the lizards will make expensive feeders for the crabs,keep it species only
thats it for now:)

hahaha no the rock cave is in my bearded dragons cage and he doesnt use it so i was gonna take it out and use it for the fiddlers, but would paint chip off or would it leach stuff out into the water?
and the second one was a question whether rocks or sand would be better for the fiddlers

also how do i replace the salt when i do a water change? like let say i have a salinity of 1.010 and i take 50% out then id have half of that right? so would i replace the half of the water with the amount that would bring it back up to the desired salinity? if that makes any since.

Simply make sure the water you add after water change is the same as the stuff you took out. I would not reuse the lizard cave if its painted.

ok thanks and my last question for today is do they need alot of land or just enough to get out of the water? right now my setup has on big rock that comes out of the water and half of its out. then i have a plant they can climb on and they can climb on their waterfall too. i can post a pic if needed. and what should i do if the filter doesnt make surface aggitation along all the water?

Make it smaller :hmm3grin2orange:
I like photobucket, very easy to resize photos through that site.

Agree with everything smaug has said, though personally I'd go with lots of rocks sticking out of the water instead of alot of sand... ended up tearing down my fiddler tank because I had about half sand and half water. They ended up digging burrows through the sand and hiding all day. Then they'd come up at night and make a ton of noise (tank was right next to my bed haha). Was irritating to have my sleep interrupted for something I didn't even get to see during the day. :sconfused:

If you want to get them a cave, a coconut hut or clay pot (or half of one) would be good... both are inexpensive and shouldn't cause any problems for the crabs or water.

my fiddlers seem to prefer staying in the water most of the time, even though I constructed a cute little white sand beach for them. And like Jackos, one my crabs has made a burrow and I never see her anymore. So considering that, I would say rocks or wood sticking partly out of the water would be preferable. I am actually considering redoing my tank (again) in a similar fashion.

Mine also really like floating wood. they sit on it like a little raft and its pretty funny when two of them try to get on the same piece and the same time.

EDIT:

I wanted to add that if you use rocks in there, avoid rounded or smooth rocks because its sometimes difficult for them to get a grip on smooth stone and they usually prefer craggy stone or driftwood.

but the crabs would be happier with the sand and isnt more about making the crabs happy and to mimic their natural habitat? and darn i have gonna add some smooth river rocks so they have more room to get out of the water :(

small rocks will be fine. They just have a hard time on wide, smooth surfaces. I have some river rocks in mine too to help support the slope of the beach.

its up to you how you want to design the habitat. I think they would be happy either way. as long as they have adequate space to get out of the water.

how should i convert the tank to brackish? ill be changing everything slowly bc i dont want the filter to loose all the bacteria, i dont want my anubius and java fern to die, and i dont want the fiddlers to go in shock bc of the instant change from petco freshwater and my brackish water. ive heard to either just replace the evaporated water with slitely salty water or do it when you do a water change. which way is better?

so i ended up getting 1 red clawed crab and have some questions. do they have the same requirements as fiddlers? how can you sex them? i heard you have to look at their vent but how the heck can i do that? wont it pinch me? can two females be together? how about 2 males? do males have bumps on their claws? thanks for the help! ill start converting the water next week! ill be taking out a gallon of water and adding enough salt to get it to like 0.004 so it will be around 0.002 with is what i heard your supposed to raise it to or was it 0.020 each week ugh!!!! how can i do that?
