Hi folks, I previously got DHG and Ludwigia sp mini. But due to poor lighting and No CO2 I almost killed them. Now i got everything good to go -7500k Top light, Liquid CO2(Flourish Excel), Ferts etc. Now my DHG is shooting up and Ludwigias are turning red, I hope that's a very good sign for plants growth. Now i want to add few more plants to my Aquascape. Right now I only have few guppies but started this tank for neon tetras. Before introducing neon tetras I want to give a good ambience to neon culture. I'm not sure about which plants to be opted for the little ones. So someone please help me in selecting the right plants. I gotta 6 Gallon tank with Hang On Water Filter. Thanks in Advance.
