I have a 6 month old betta that has developed a lump on his head, behind his eye. It was small at first, and now has grown to be rather large. He is in a 3 gallon tank, and I have done a complete water change several times with no improvement. I have also dosed with Melafix and Bettafix to no avail. He is still eating, but I am worried about the size of this lump. I cannot seem to find information on this kind of thing anywhere. Please let me know if anyone out there has any insight.
I also have a female betta, about 2 years old, and she has not been eating for the past week. I have been studying her, trying to find out what is wrong, and today noticed a stringy white substance hanging down from her belly. I can't tell if she's off color because she's white, but I don't know how much longer she can go without eating. Please help!
I will post pictures of both shortly.
