I am looking for some advice for an aquascape I am planning. I would like to grow some carpeting in my tank with dwarf baby tears but am not sure what substrate would be best. I read that you could layer a finer substrate over fine gravel for rooting, but I am new to this and thought it best to check recommendations here. I was thinking about planting with fluval stratum and sand on top? I have some neo shrimp in the tank and one male betta.
