Also you're gonna have to keep them well fed, I was reading his site and one day he missed the normal feeding time and took a nap, and lost a fish in one pygo colony. He has quite a few interesting ideas, some people will agree with them and som disagree. Just because he did it, does not mean you can do it.
I'd say if you try that, (other people other than alan have and have been successful), I would say, big tank, lots of hiding spacies, good amount of plants to provide cover. Feed daily, maybe twice a day and get rid of extra food that is left over. Have an open hospital tank.
Most people will disagree and say don't do this. Read up on it, read everything that he did and then see if you can recreate what he did. Also, if you have the money, then do what you want.
Also the temperature thing, lower tempature should be less active. Yes, but one thing you gotta think of is the temperature change daily of up to 20 degrees. So 75 really wouldn't be punishing or hurting the fish. Personally though, I keep my tank at 79-80.
