I took a look at the photo of your 29g, which i assume is the tank we are discussing. Definitely get some floating plants, Water Sprite if you can find it; Brazilian Pennywort works well floating. And Wisteria will float too, as someone mentioned already.
Are you using any plant fertilizer? Which one if yes, and how often?
Gravel is a bit large, but it looks smooth; main thing for corys is no rough substrate material. You could change over to play sand, up to you, but if you think you might, do it now before you get more fish and plants. And corys need to be in a group, 5 is minimum; you can have 5 of the same species, or if you want variety, have two species with 3 of each for a total of 6. We have several species in our profiles, under the second tab from the left in the blue bar across the top of the page. The Pepper Cory is included, and the name shaded so you can click it for the profile.
