Having a goldfish get egg bound is very uncommon, but it has been known to happen. Signs that the female is in trouble include being very swollen, having trouble swimming, no appetite, and spends most of its time on the bottom.There is one treatment that is said to sometimes help a fish to either expell or reabsorb the eggs. This is giving the fish a bath in water with Epsom salts. Goldfish keepers use 1 tablespoon of Epsom salts per gallon of water, and leave the fish in for 15 minutes once a day, and no more than that. Also consider keeping the fish in a hospital tank during this time and treat with Maracyn, as it helps prevent infection from any retained eggs.
