Foreground Plant Suggestions

That's a good amount of light. Depending on the age of the bulbs and temperature, HC is always a nice foreground. The pleco might be a problem because it can take some time for HC to root.

With that much light, I assume you have co2. If so, I suggest E. tenellus or Blxya japonica. Both are very nice foregroudn plants for tall tanks and root fairly quickly so they won't be dug up by the pleco.
