You people and i'm not directing this at Bill, who want to assert survival of the fittest tactics and think you're on to something then for all of our sakes establish guidelines and be very specific of all details of your systems and practices - i.e., include vital information such as: LxWxH, size of display tank, % of open swimming space, total # of gallons, numbers, size and species of fish along with dates of purchase/release into your display tank, inverts present and their numbers, plus number of tank set ups in the household and frequency of new fish, introductions of live food sources e.g. lv brine shrimp, clams, mussels etc., dates and frequency (i'm sure i missed a few). "Maybe", then we can get a baseline pattern of your success and failures. That is if you've enough years of long term success to back up any of your claims. And please spare me the rational, because i disagree doesn't mean i don't get it, i'd like to see this move up a level.
And again well i can't promise i'll participate further, at least we'll be getting somewhere past the he said she said therefor it must be mentality.
