They are the easiest of the sulawesi shrimp, in my opinion. I kept them a few years back, when they first entered the hobby. I was able to keep and breed them with a very simple set-up that I created overnight.
Crushed coral at the bottom of the tank, a thin layer.
Sand on top, about 2 inches.
Some random rocks I collected at a nearby creek.
One sponge filter
One heater set at 80-82F
Add tap water
Purigen bag (I added purigen because I literally set this tank up the night before they arrived)
My tap comes out 7.6 ph, I'm sure the corals must've raised it a bit. I never tested for anything else. I found my tap to be perfect for em and the one thing to be aware of is temp. I don't let my temp drop below 80. My heater malfunctioned before and my tank hit 90F, they were perfectly fine still. I didn't catch the malfunction till after a day or two, I think. They can withstand a lot of heat! I wouldn't recommend keeping it past 85 though...
