Hi Brad. Beautiful fronts. If I may suggest something, to avoid future injuries. I'd ditch the rocks and switch them with smooth river rocks. Lava rock is too rugged and Frontosas are really skittish sometimes and they usually dart and hide under, or chase each other ...rugged rocks can be the cause of injuries.
If you're concerned over the pH value you can use aragonite sand as substrate (you don't need a lot of that - I have one bag in my 400gal and it's perfect pH all the time).
