I believe his table is showing each male and female morph he has. Just sayin..
To the op: in my opinion, hold off on animals for a bit and invest in a rack with flexwatt heat and a thermostat. Aquariums work, but are not very space efficient when you own multiple snakes.
Then, if you have open slots available in the rack, get more just my opinion.
