This is especially true if one of your ghost shrimp happens to not actually be a ghost shrimp but a Macrobrachium sp. If your ghost shrimp don't pick on the cherries your gourami or tetras most likely will. You can kiss any shrimplettes goodbye and if the fish feel like they're underfed you can kiss the adults goodbye as well
Actually I was planning on replacing the ghost shrimp in favor of the yellow as I had read about problems and saw a YouTube video of a ghost eating a yellow.
The fish haven't bothered the small ghost shrimp (maybe half full adult, possibly a third) so I don't think the fish will be a problem. The gourami is a piggy but incredibly nonaggressive. The cardinals kind of shoal around him.
