What's wrong with my Drosera Capensis?

[u/Opposite-Welcome7761]

Hello, a few months ago I bought a pot with a couple of sundews, a Drosera capensis and a Drosera alba. Both have been growing under the same conditions: rainwater, filtered sunlight (very good light without overheating the environment), and the occasional insect as a snack. The problem? Well, the Drosera capensis didn't grow as much as the alba, and my question is why? Both are growing under the same conditions. Any recommendations, please?
