Ive had my 29 gallon tank for a while now and have had no problems with illnesses so one day i was looking at my angelfish pair and relised one of them has like a white thing on its eye. It sort of looks like a tumor but not at the same time. Ill try to post some pics later. To tell you the truth i have no clue what the levels are in my tank but i will get them to you guys as soon as i can. All the other fish are doing fine and show no signs of getting it. I did do a 30% water change the other day with the gravel vac. So does anyone have any ideas? I dont want he\she to die.
