Hello, I'm new to the forum. I have a 3-4 year old male betta living in a heated 5 gallon aquarium, gravel, filter, treated tap water, silk plants, and an acrylic pillar decoration that I sanded sharper edges off of. He gets fed the betta pellets about every other day and occasionally freeze dried shrimp. He's fairly large (3-4 inches) and highly active and spunky (he flares back if you put your hands on the side of your face as if you're flaring at him). He used to live in a 1/4 gallon bowl with a plastic plant for a year, then he upgraded to a 1 gallon bowl for a little over a year, now he's in his 5 gallon bachelor pad. I figure I'm doing something right if he's survived this long *knock on wood* seeing as I could never keep fish for more than a month prior to him.. Perhaps he's just a fighter!
Anyway, my question is.. I have about 3 medium sized silk plants and 4 small silk front plants in this aquarium with 2 of the larger ones in front of the filter to break up the flow.. but I've thought about getting a live plant. Would it be too much to put in a piece of java fern? I'm concerned about the java fern from a pet store possibly carrying contaminants, snail babies, etc.. What are the odds of this? Or would a betta bulb work? I don't have a problem with algae either, he gets more of the morning sun/ambient sun than direct light.
I'll post pics of his set-up in a bit, if I can get some better ones.

Edit: Here's a link to his aquarium set-up
