Nah, I decided to try java moss as a secondary fast grower. The water sprite's already taking over the top.Did you decide to try some cabomba? It would grow fast for you and should do fine. I had some in my low tech and it's like a weed.
I need the moss to cover the bogwood, as it looks too plain and I can't seem to convince the baby sprites to sit on it. They just float right back to the top.
Still waiting for the day my dad will get the moss though. -.-
