You can tap into the cold water supply of your house for a DIY low cost chiller.
Use a refrigerator ice maker hook up kit. Add 200 feet of 1/4" poly tubing coiled in your sump and out to the drain. Add a "normally closed" solenoid from a washing machine and a temp controller and you are done...
I have been thinking of giving one or two a try. If you could relay any experience that would be great. Is it possible to breed these in captivity?
Thanks in advance.
