That plan is definitely overstocked. I put 6 each glowlight neons and harlequin rasboras and was at 40% for a 29. I'd go with just the danios, neons, and cories and see what aqua advisor says. I have just small fish in my 29 and don't feel an absence of a large centerpiece fish. I chose glowlight neons and rasboras, they look similar and school together so that group is my centerpiece.
