Good fry tank plants

HI everyone! I am planning on setting up a 10 gallon spawning and rearing tank for my Betta smaragdina pair. What are some good plants I could include in it? I was going to include floating plants and perhaps CO2 injection for the non-floaters; since this is going to be a fry tank, most fertilizers provided will be for potassium and trace elements. Thanks

 

Hornwort works great for fry to hide

 

Thanks! I am also interested in the plants being both easy growing and good nutrient consumers...granted, hornwort is both, but are there any other options I can use in addition to hornwort?

 

Guppy grass is another good option

Water sprite can be planted or floated. It's pretty much unkillable, so that's a good option

 

Would floating plants work better for nutrient extraction, in view of the easier time they have getting CO2? Also, would the large amount of food (1/8th tsp a day maximum for this tank) add enough phosphorous for the plants? (I am not expecting nitrogen deficiency to be a problem)
