Hello, is it okay to add live plants to an aquarium that has fish for a month but no plants? I have ordered a few that may arrive this week. I dont have soil substrate in it either. The plants i ordered include dwarf water lily, java moss, duck weed, hair grass and dwarf hair grass. I have 3 male guppies, 5 female guppies and 3 neon tetras in a 10 gallon tank. I would really appreciate any help on this.
