Red Aponogeton

Smaller peice then the picture and what i expected but thats my fault for expecting exactly like the picture. My plant is greener then the pic but many red hues. Expecting it to get redder and bigger.

Bought 2 of these. 1came red and other is green. Planted both on same aquarium. 1 kept turning really red. The other is still plain green. I have a feeling that the other one is just a regular Aponogeton Crispus. Even the new leaves are green.
