Since you're a beginner, I'm assuming you have a low tech setup without high light or CO2. If that's the case, you don't have many options in terms of carpeting plants.
Some species of hydrocotyle like hydrocotyle tripartita might be a good bet, but it will grow taller than it would in a high light tank.
Most species of plants will do fine with bettas. If you explore your search on the webs, you will hit tonnes of info.
To start you off:
- s. Repens
- dwarf sag
What light, substrate, fertilizers do you have? CO2?
No fertilizers, standard light that came with the 10 gallon, no CO2 I can get whatever substrate you recommend.
Standard lights won't cut it, but if you upgrade them and get a soil substrate I think you could do well with monte carlo. aussieJJDude's suggestions are also good
