when ever my fish get ich (usually when i buy new fish) i double up air suppie double up filtration if it ainte already. add a lil Aquria salt raise tem to 86 and wait and hope for the best. maybe your parameters were a lil bad? to hard of water? to high nitrate? the possiblilities can go on.
but that sucks man =( i know how u feel.
