Definitely a pretty boy you have there. (: I've seen pictures of female bettas with as much colour as males and long finnage, but never like that. Where did you find him?
Your Trichomanes javacium, which is Aqua Fern/Borneo Fern, probably died because it is not a true aquatic plant. White Ribbon/Dracaena sandriana isn't an aquatic plant either. They will eventually rot and die if submerged in water. Be careful buying plants from petstores, especially from Petsmart and Petco; a lot of the plants they sell for aquariums are not really aquatic.
Also, I'm not certain, but your Anubias plants look like peace lilies (Spathiphyllum wallisii)...
