Centerpiece fish

Rams would definitely eat any shrimp they can get a hold of. Mollies get too large for a 15 gallon IMHO.

Peacock gudgeons would be sweet but might make it too bottom heavy? Maybe balance it with some small tetras like embers or something then.

I've had both GBRs and Bolivians and none of them ever went near any of my ghost shrimp.
