If you have the courage, use a pipette and put a few drop of epsom salt solution directly down the fishes throat. Otherwise, (what has worked for me quite a few times), is to treat with Tetra Parasite guard for the maximum amount of treatments (which I thinks is 3) per the directions on the box. After the last treatment, the fish starts to eat again, and I feed the epsom salt soaked pellets for 5 days.
