I originally posted here on 8/9/12, when I noticed my fish had a "blotch" on him. Well, it stayed the same for a while, so I thought is was just coloring, as another member had suggested.
As of a few days ago, there has been a change. Now it has turned into a white spot. I'm not sure what to do.
Norm lives in a 3 gal talk, alone. I got him in March, '12. No filter, no airstone, just bought a heater two weeks ago (we live in Michigan and its getting colder). Heater factory set a 78 F. I change one gallon (1/3) of his water every week to ten days. I feed him Aqueon Betta food (only).
I will post the original as well as today's pic. Thank you for any input!!!
