Along with the addition of the co2, we introduced some livestock: white cloud minnows, a nerite snail, amano shrimps, and some more otos. We also moved our neon tetras and one remaining amano shrimp from our 10g to this tank. It's a nice community we have now.
We also added some new plants: frog bit, rotala vietnam, and hydrocotyle verticillata (we have been calling it the "pogo" plant).
The scape was also updated with ryuoh stones.
