My waterfall, which doubles as a giant bird bath, makes for a great fluke provider. lol Need to still pull for physical exam but saw this thread and though I would jump on.
If the breaching and bubble blowing is isolated to around feeding time, the fish will get crumbs/dust/food particles in the gills and do the breach and bubbles to dislodge it. If it is occurring at other times, then look for parasites.
