Carpets are difficult to create if you don't have the right conditions. What type of equipment do you have? CO2?

In a 10 gallon, you will need really small plants to create proper perspective and proportion. Glossostigma may work but also Hemianthus callitrichoides "Cuba".

Based on your set up, I would recommend dwarf hair grass or microswords. The others are too demanding and don't do well without CO2 and a high-tech setup.
