My ( red texas ) got it from petsmart so possibly a flower horn has become very bloated. Over the past few weeks he has struggled to stay alive, so far i've been doing a 20%-40% water change every day and am adding epsom salt. About 1 and 1/2 TBS to the 10 gallon tank, i've added jungle parasite clear tabs in the begging but not any more as it seems they haven't helped. Hes gotten very skinny from not eating and now he has a large white bump extrudeing from his side
