Sounds like a lot already. If you stick with the 1” per gallon rule a 10 gallon shouldn’t have more than 10” of fish. Even if we count each kuhli as only 1” since they’re so skinny (I would recommend counting them as at least 1.5”) they’re still 5” or more inches worth, plus a dwarf gourami is at least 2”, plus each platy you have to count as at least 1.5”-2”, then your glow lights are going to be at least 1” each and that’s all light estimates. If you switch out glow lights for barbs you add even more inches since the barbs are significantly heavier bodied and larger overall.
While you certainly can push the recommended limits it will necessitate more frequent and larger water changes, more frequent testing, and you run a much higher risk of losing fish. If you lose even 1 fish while you’re gone at work, the toxins produced as the body decomposes for even a few hours will significantly pollute the tank and could kill everybody before you get home.
if you want to have more visual impact, maybe make it a barb only tank, or barbs and kuhli loaches only, but don’t push the limit too far or all of them could pay the price.
