Tank Stocking Suggestions please

Hi. Need some help with fish selection to eventually fully stock my tank. It’s a 6 x 2 x 2 foot aquarium, has a sump of 120x26x30cm. I recently upgraded from a 65liter tank. So far I have 2 Dwarf Gourami (might have to rehome one as they are fighting), 8 Danios (leopard, pearl and zebra), 6 neon tetra, 3 phantom tetra, 4 glass catfish, 2 Sterbai Cory, 1 Bristlenose. Thanks!
