Will 10 Neon Tetras 10 Zebra Danios 2 Peppered Corys and 5 Ghost Shrimp be okay in a 29 gallon tank?

They will go fine - try to use a fine gravel so that the cories can root around nicely - maybe even consider adding a few more cories? bring it up to 5 - they will be much happier. Keep the PH at 6.5 - 7 and make sure the ghost shrimp get enough food - they can starve. Good luck
