@Matt it sounds cool but your link is not working for me.

My new addition to my automation: my WiFi fish tank temperature reader.  Let me know what you think.  Allows you to view your temp via the web, and will also send you email when the temp gets to warm or to cold by triggers you can set.

P.S. Yes they are cannibalistic and often need shelter such as stacked 3-4 inch PVC tubes for best results.

Greetings all.  Their environmental requirements are much the same as for tilapia but they are not at all cold tolerant. 70F is about the minimum. They don't like copper in the water and since their shells are made largely of an organic version of calcium bicarbonate, probably 6.8 is the lowest that you can go with the pH (need to research this one). Unlike tilapia they don't do as well in poor water quality including needing a reasonable amount of oxygen.

Regarding density, first I would disagree with those who suggest putting them in your IBC. They from my experience will not do well there. However as suggested by many, they do reasonably well in DWC grow beds. Because they are a low density product, you can't get all that many of them into your system at one time. I would suggest 1 prawn for every 2.5 square feet of DWC growbed space for now. Depending on how you manage your system you may be able to do better in time.

What are the temperature requirements for them?
Comment by Matt Miskinnis on Saturday

Dr Brooks, with the shrimp, is it more about the separation and hiding places?  I would love to try raising shrimp but I would think you would need a much larger tank because each shrimp would need so much space or they will attack each other.  Am I correct on that?

Wow! What a concept. This will be interesting.
