my angels and amanos were fine for a while... but by the time the angels got close to adult size, everything started to hide. the amanos survived, but only by hiding 100% of the time. even the snails i had were targets for the angels... they'd pluck 'em off the glass and crush them and eat them. heck, my angels even ate my duckweed! angels are "peaceful" fish... but anything that can fit in their mouth, they will eat. and i doubt your cherries would stand much of a chance unless you provided LOTS of cover. LOTS. but then you'd never see your RCS, either.
