Yellow Bellied Slider and Plant Life

[MKeim1989]

I know its been a while since I last posted anything at all but the last few months have been extremely trying for more reasons than one. Last May, I lost my little brother to a car accident. Because of this tragedy, I also inadvertently adopted a yellow bellied slider. My brother received this turtle as a gift from my parents and the three of them became three more victims of commercial pet chain misinformation.

Knowing next to nothing about turtles, I did my research and I've fixed a lot of the problems I found with his set up. My question for those more knowledgeable is in regard to plant life. I've read that adult sliders need a lot of plant matter in their diets and I'm wondering if there are any type of aquatic plants that could be planted in the turtle's aquarium that would be fast growing and hardy enough to sustain his herbivore side without him completely obliterating them.

I know next to nothing about aquatic plant life, so any advice in that area is more than welcome. Also, any tips for a new mature yellow bellied slider would be appreciated as well. I also encourage any info on your own setups including substrates you use as I'm curious as to what you guys think is best.

Thanks in advance.
