I used to work at a pet store and we got a bunch of Apongeton boivianus in.
They over took the tank. It was a 103 gallon tank that was about 33" tall.
It had so many leaves. Covered more than 1/3 of the tank. Fish loved it.
Beautiful but too "big"
Yeah, this plant does get too big for any but the largest aquariums. But it
throws off babies left and right, so you can always get rid of the mother plant
and replace it with a baby.
