Do i really need co2 injection for Java moss...help!!!?

Here it goes i have a 26 liter aquarium or about just under 10 g (6.something) and i want to put some java moss..not the brown type but the green type and other plants inWhat do i really need??(don't have it yet ) I already have gravel in the aquarium i also have 3 big guppies..and small ones as well,7 neon tetra, and 7 white cloud........Is it necearry to put in solid fertilizer as well as a c02 injection device...right now all i have in the tank is an air pump,gravel, filter ,and D/W Drift Wood and a small house for decorations.. does java moss need co2 injection(tank) or Diy co2 (yeast) , fertilizer ...and will the java moss actually grow through gravel if i use gravel to weigh it down instead of D/W too see what i'm talking about type in MELVENWONG89 in youtube to see..the plants in the aquarium have wither and died but i was thinking of getting the same type again..but without co2..is it possible..
