Your small, black gnats are Fungus Gnats. They live and propagate (as larvas) in moist/wet soils.
First step is to keep your soil on the dry side. 2--put sharp sand or powdered up egg shells on top pf the soil. Best would be "Diatomaceous Earth" which is powdered silica.
See what the article can do to help you--or--Google "eliminating Fungus Gnats from houseplants.

TennesseeDave said:It's definitely one of the Calatheas. Of all the plants that I have ever tried to grow the Calathea is at the top of the my list as one of the most difficult. For a Calathea to thrive as a house plant, high humidity, warm temperatures and lots of water are needed. Your plant is suffering from lack of one or more of those things. I love these plants (particularly the Peacock) and wish I could keep them looking good but atlas this is now a summer annual on the porch for me. The lack of humidity in the house as been their downfall for me.
