Plant recs my tank seems empty
Tank:17.5gals(80 litres)
Does anyone have any recommendations my tank seems so empty especially in the middle I was thinking of getting a piece of wood in the middle with mosses on it but idk tbh would that be easy to do or not? Like idk if it would be low CO2 as well any recommendations would really be helpful ngl I added some of the ones I was thinking about but I’m honestly so unsure😭but I’m going down tomorrow for some as my fish shop sells all of those ones in the second picture
Btw tank is cycled and parameters are all completely fine so decided not to include
