Bullhead, some fish will die fast, some of the more sensitive, smaller fish will be launching themselves out of the water, but most of your BH will endue a rather gruesome demise and suffocate as their gills are burned. Your bullheads will burrow into the mud, so be sure to treat any mucked up areas above the pool level pretty heavily. Also, if possible, rake the pond muck still under the main pool to get the caustic water to any hiding BH. The lethally high pH will only last a few days after application...
