I'ld say between slim and none unless your fetermined to raise them and get somewhat lucky. If they are on somehing removeable i would isolate them in another tank with good water flow and very little algae growth. If they do hatch in the tank they will surley be eaten or taken in by the filtration. as for feeding usually only rotifers will do. rotifer cultures can be made with a 2 liter bottle and some light along with a purchased rotifer culture. aside from that not much else will fit in a clown larvae's mouth.
