I haven't really set anythign up professionally yet. Usually I just add tap water, let it sit overnight, then add cheap fish to the tank before I add expenisive ones to it. I have never really had any problems with sickness or deaths.

But I am thinking of setting up a real nice lookign tank and I want to do it all professional like.

This is the setup I am looking at. It will be a crab and fish tank. As for filters and such, I am still looking into things. any suggestions would be nice.

What I am looking for:

30-50 gallon tank. Not sure, right now leanign towards a 31 gallon tank kit. But I aso wait a bit till my job picks back up and I can go and buy a 58 gallon kit. Both kits contain stands, main reason why I want to buy a kit.
Crab contents: 2 halloween crabs, at leats 3 gold fiddle crabs, possibly other FW crabs if I can find them
Fish: unsure of yet. Possible fancy guppies

Note sure of filter, lighting, and other stuff. Like I said, this will be my first professional quality tank.

You might be able to help me with the setup of the tank as well. Do you think crabs would be smart enough to figure out how to get from the bottem of tank to the top dry land? The dry land will be 4' deep, giving the halloween crab somethign to dig in. Do you think 4" would be enough?

Also, seeing as the dry land will be blocking off any source of light from above, is there plants can live in this shadowed area? This dry area will have a surface area of 12"×8" roughly. Also, I run into the same problem with the "platform/step" in the middle of the one side of the tank. It will be about 12"×4". And the same problem with the "stairs" that go from floor to platform to platform. They will be about 3" wide I am thinking.

When thinking abotu this, I am also come up with another question. If I wish to put any plants on the "stairs" or the underwater "platform", what should they be and how deep of gravel (or whatever I use) should I have? Is 1" good enough? Also, what type of gravel do you think would be best for this type of tank?

Another thing, how would you make the surface of the "stairs" non slip so crabs won't find it hard to climb? I was thinking of either gluing a gravel or soemthing to the surface of the glass (if I use glass) stairs. I am also thinking of possible making a tray like stair, so I can put an inch of sand or soemthing for plants to be planted on stairs. If I did this, do you still think I would need to glue a layer of gravel to the glass?

Okay, so a refresh for this post. Here are the questions I have:

1) Do you think crabs will be smart enough to find their way from bottem of tank to dry land at top?

2) Will a 3" 'stair' be large enough for a full grown halloween crab or will he tend to fall off due to be too large? (Not sure how large they become at full size)

3) Will a deepness of 4" of sand on the dry land area be enough for halloween crab to borrow in?

4) Will a area of 8"×12" be enough dry land for two full grown halloween crabs?

5) How would you make the surface of the stairs not slippery so that crabs can climb it? Would you glue gravel or would making a tray like stair(so that sand or gravel doesn't fall out) would be enough? If I go tray style, should I still glue a layer of gravel to glass stairs?

6) Whats the best type of glue to use? Silicon or something?

7) Are there any plants that would fair well in a location where they wouldn't get much light due to a stair or platform above them? What about on the stairs, which will plenty of light, what would fair there?

8) On the bottem of the tank, how deep should sand or gravel be?

9) What is the best planting sand or gravel that would work in my type of tank?

10) Do you think the setup of my tank in the picture will work or will it make to much of a hassle? Is their another more creative way of making stairs for crabs to get to higher parts of tanks? I was thinking of possibly making a custom background for the tank with stairs built into it, but unsure of how I would do this and if climbing back and forth on one wall of the tank would be harder then circling along the edge of the tank.

Thanks in advance for any help.

As far as stair for a crab, as I have had them before, I used the wooden ladders that petshops sell for birds. I usually bought 2 long ones, as I have a 20 long tank, and binded them together using zipties.

I don't know if you have had crabs before, but make sure that your tank is completely sealed up. As they are very smart creatures and will find a way out, if there is a way out. To follow a long with that, you don't have to worry about them trying to get from the bottom to the top, as they will find a way. When they want to get out of the water, they will find a way.

Well, first off, it sounds like a very detailed and creative idea you have come up with. I'm having trouble finding information about "halloween crabs". It seems they are actually called "halloween moon crabs", but still not much luck on finding any research about them, either. here's a site where one person talks about the care of these crabs from experience:

It seems that sand is their best flooring.
They eat fish.
They eat plants.
They like wood (to eat).
They are territorial.

As for plants, I doubt anything will actually grow if it isn't getting any light at all. And being as how your crabs will eat them, I doubt they will have a chance to grow anyway. Also, maybe it will be easier for you to just take the back half of the tank and make one straight slope from one end to the other. This way you can make it wide enough for him not to fall off, and I imagine he will be ok with the slant.

I hope I've helped you a little bit. These guys are really pretty.
