I'm keeping Apistos with various types of shrimp (see sig) but I'm sure the male will start picking them off. I've seen him stalking a cherry once or twice but they always manage to jump out of the way but it's only a matter of time. Shame really.. The larger Amanos are fine but I've got a few baby shrimp in the tank at the moment (they look like Amano but can't be so can only presume they're tiger or cherry etc., they just haven't coloured up yet) and at the moment they're near the surface on the leaves of the plants out of the way of the bottom dwelling apistos etc. However, I would imagine that adult angels would make a feast out of your shrimp eventually.
