Super sweet tank! I love the aquascaping!!!
The plants look like young lilly pads, or a smaller species of lilly pads, if they are, then the leaves will end up growing to the surface and laying on top of the water. IF they are regular lilly pads though they will get HUGE. But hopefully they are a dwarf species or something, cause they look good.
Out of couriosity, would you mind shareing the size of your tank in gallons and dimenstion? thanx
