Boraras (dwarf rasboras)

lol 5"...they are full grown!
 
Very nice tank!
 
Cool little fish! Is that a CO2 system I see in the back?

In the back left (actually left side of the tank) I have the AC filter and a limewood airstone under the outflow diffusing diy co2. Works good, get bubbling at the end of the day but im sure i dont get 100% not even 80% diffusion.
