Cryptocoryne minima in blooming spree

When I cleaned my setups today and looked closely on my plants. What a surprise when I found spathes in both pots. In one pot, I even have three of them. Both pots are already full and plants have many plantlets.

Sorry for poor quality. Since I don’t have macro lens, close up filters lower the quality.

I guess I need to lower the humidity and vent it more to get rid of this algae/fungus.
