Sulawesi shrimp are the newest shrimp for the hobby. They are very expensive running 12-15 bucks a pop. They are also very sensitive, needing very specific water parameters.
Parameters should be almost exactly as follows:
PH of 8.0-8.2
Temp of about 82
The best way to achieve these parameters is to use water with the correct GH, the PH and KH of the source water not being important as the crushed coral will take care of that. The substrate should be crushed coral. Many people mix the coral with sand because it looks a lot better that way. You also need to use water with the correct parameters for water changes, so you will need some kind of bucket with crushed coral, a heater and an air stone in it. These shrimp are so sensitive it is not recommended to do any more than 10 percent water change at a time. This should be plenty however as you shouldn't be keeping these with any fish.
More specific water paramaters by lake, thanks billb!
Water Parameters Towuti Lake - Harlequins, Redlines, Red Orchids, Yellow cheeks and many others are from here
Temperature average: 30 C
Ammonia, Nitrite, Nitrate: 0
Iron, Copper: 0
Water Parameters Mantano Lake - Where Cardinals are from
Temperature: 29.5 C
Ammonia, Nitrite, Nitrate, Iron, Copper: 0
But having correct water parameters alone will not suffice to keep these shrimp. They even more sensitive than other types of shrimp known for being tough to keep such as blue tigers, black tigers, and SSS crystal red shrimp.
The tank should not be heavily planted, these shrimp like to climb around on rocks. Lava rock works best. You want your rocks to be stacked so that the shrimp can be in nooks and cranny around the rock work, and also hang out upside down. They seem to like this. Some moss is good, but not covering all the rock. Driftwood is present in the lakes as well, it looks a lot like manzanita (sp?!) which is sold on this forum in the SnS, just do a search.
You still need more than a good layout and good parameters to keep these shrimp though. A freshly cycled tank is doomed for failure. The tank should be well established with lots of bio-film. A good way to do this would be to use the tank for fish for a few months then switch it into a shrimp tank. These shrimp will also appreciate Indian almond leaves, but don't use too many at once or it could reduce the PH. This is unlikely however unless the entire bottom is covered in them. One or two at a time is fine.
These shrimp eat the same stuff as other shrimp. Just remember not to overfeed or feed too much protein. Both these mistakes kill shrimp.
Try fresh veggies, algae wafers, shrimp pellets, and specialty shrimp foods like mosura and shirakura(sp??)
Here are some pics of the lake if you want to do a biotope
OTHER SULAWESI CRITTERS
Tylomania snails make good tank mates, they are very large compared to pest snails growing to several inches as adults. They give live birth to a single young snail at a time. Some species eat plants.
Many awesome fish are from the sulawesi lakes as well, but they are not available in the hobby as of yet with the exception of one goby species. Others maybe but very hard to find.
some people on the forum sell the snails from time to time such as mgamer20o0 and ZID ZULANDER. You can PM them if you are looking.

Here are some good pictures of the Malili lakes and the shrimps natural habitat

A photo journal of a collecting trip to Matano and Towuti (in German)
A thread in Arizona Inverts with the english translation! look down a couple of posts
A scientific paper describing 8 species of Sulawesi shrimp and some notes on habitat
I saw a post with a link to German site focused on diseases of shrimp and crayfish! Unbelievable! The German hobbyists are way ahead. Here is a link to the Google translated site:
For those interested, I did find a very useful paper that was recently published on Lake Matano water chemistry. Here is the link
If you can't open the file, do a google search on this title:
"The biogeochemistry of tropical lakes: A case study from Lake Matano, Indonesia"
In a nut shell - this is an ancient and stable lake. The upper water layers are clear and nutrient poor (oligotrophic). Low P, N and organic matter coupled with fairly high Chromium and Nickel concentrations. These metals may contribute to the low abundance of phytoplankton.

Any other questions, just ask and I will edit the OP to be more complete!
*Please note I am not an expert on these shrimp someone just suggested a write up, so this is a start and I will make changes based on peoples responses. It is possible not all this information is 100% correct this is a work in progress and is based on my knowledge of reading various sources.*
