My 20 litre freshwater aquarium (week 8)

My aquarium 8 weeks after set up. It’s well cycled now and the plants are growing. I had brown algae all over the aquarium a few weeks ago, but it looks like they are disappearing now. I know this fish tank is slightly overstocked. Fish are healthy and happy though. Will probably move some fish to another tank when I get it. I usually don’t have this many bubbles in aquarium. This video was taken after a water change when the bubbles get caught on the leaves. I’m running a home made CO2. FYI 20 litre = 5.3 US gallon
