Thank you. I'm never quite satisfied with the tanks, I re-arrange & add more plants, some plants live & some not so much but yes I think the fish are quite happy, at least I hope they are.
Thank you! Yes he is my betta, named Cinder :D I'm honestly not sure what color he is but he definitely has black on the outside ridges of his fins and his body is a coppery-metallic color that seems to change in the light to purples, blue and turquoise. He was the only black one I could find at my Petsmart, and originally I was about to buy a blue one but then I saw him!
