First off a 26 gallon just isn't big enough for angelfish unless your planning to get a much larger tank within about a year. Also you will only want to plant 1 Amazon Sword as they get very large. It may seem small to start but they get big fast and take up alot of room. There are also alot of tall plants but what exactly is the lighting your using ? T5HO's, T8's, ??? Plants would be Water sprite, Wisteria, any stem plants such as Ambulia (my favorite), Anarachis, Temple, Cabomba, just to name a few. You can also float water sprite or most stem plants if you want but in a tank that small I don't think I'd float any. You will also need root tabs even with a dirted tank (I have a 220g dirted tank) especially for Swords and Crypts. Another nice plant that will add color and grows very good sized are Red Tiger Lotus. Crypts make good mid to forground plants and don't require high light. You'll need to get either a liquid fertilizer such as Flourish Comprehensive to dose weekly after WC's or if you really do have high light and alot of plants dry fertilizers might be in order. Also with high light tanks you need to consider using a liquid carbon such as Excel or doing CO2, either DIY or Pressurized.
