Thanks, Ken! I'm glad to know I'm not the only one piecing together a larger tank while still trying to learn the plants and all.
I pulled out the largest val, cleaned it up, and stuck it in my 75. I'm not using my TEK lights on it yet so I don't think the hair algae can survive there. If it does, there's always my amano shrimp.
I'm thinking of doing some kind of little scene with this tank just to play around. Maybe a winding pathway with small river rocks in the middle with some hills and valleys. My craziest thought at the moment is to consider using java moss as a lawn. It's no different than a moss wall, only on the bottom. The tiny leaves is what I'm thinking of using it for.
Just ideas for now.
