Well the retic and burm situation I have no idea about, but the columbians can usually thrive for a long time in the sterilte 1996 74qt sweater totes, they are 4ft long, 2 ft deep, and 7 inches high. After that you'll probably have to go with a six foot rack (Freedom Breeder) or a Boaphile Here (It's not a rack, but they are really close to one). Freedom Breeder has some nice racks that are more than big enough for any BCI or BCC Here The bloods will be good in the Sterilte ones too.
