Albino Corydoras and kuhli loached?

I'm currently stocking my 20 gallon long tank and i was really into getting corys and kuhli loaches together, maybe 5 of each cause thats what ive seen was best online. but theres also people saying they wouldnt house them together so im just curious about some personal opinions.

would this be okay or is it over stocked and i should just choose one or the other? if ive gotta choose id pick the corys lol but loaches are just so intresting.
