I have a discus that i believe is constipated has a round lump by his anus. i've been using epsom salt 1tbsp per 10gals. in my 55g. daily for the first three days and then every other day since last monday. lump is still the same size and his feces is still white. any ideas anyone? temp of tamk is also 84 degrees if that matters. all the discus eats is bloodworms and cichlid flakes cant get it to eat any peas.
