No... I removed the gravel a few days after I had her, which was more than a month ago. She hasn't had anything in the tank since, except marbles, which are WAY to big for her to eat (there to anchor the live bamboo down)

I noticed today she came over to me, which was a first...

I still leave food in her tank; however I dont know if she eats them, or if they turn to mush (theres mush at the bottom of her tank at times)
