I would also suggest getting some Flourish root tabs to help your plants with the regular gravel.
The grass plant, is that mondo grass? If so, that is not an aquatic plant and will eventually die. Also, make sure you don't bury your Anubias' rhizome otherwise, it will die too.
Great start btw!
I could be wrong but it does look like mondo grass. If that in fact is mondo grass I would remove. Mondo grass is not a aquatic plant.
