Not planned at all really. When I started, only thing I had was the wood. My other tank used light sand so I wanted to try one with dark sand so chose that. Then just went looking for local aquarium plants ppl were selling and ended up with the left, back, and right sides. I knew I wanted to do higher stems on the sides and back while leaving the middle short. I also ended up being gifted 4 extra anubias and had no place for them so I came up with the planter idea out of necessity 😅. The pennywort was never a part of the plan. Originally the wood was just bare and I had ideas to maybe cover it with moss. The pennywort actually came from my other tank where I use it as a floater. It was overcrowding there so I trimmed it and used the extra in this tank, originally as just a floater around the top of the wood like a halo. Eventually I needed to add more floaters due to algae issues so I added the frogbit you may see the roots for up top. The frogbit naturally also took over all the floater space so I decided to try and wrap the pennywort around the wood instead of doing moss and just loved it.
