Sugar coating and nicely nicely? I don't think so
I'd plant that tank up to bursting point, get it looking great and stock it with an absolutely VAST shoal of something like Chilli rasboros , Normans lampeyes, or some other single species of really small fish that will pack together in a tight block. Then perhaps add a group of centrepiece fish to really stand out. Moonlight gouramis for example.
That would look seriously stunning.
