Hello! I recently got my first beta named Emerald Herald! I've been doing lots of research (including on this forum) to make sure I give him optimal conditions. However, he seems to have developed (I believe these were there when I got him, but they look worse now) some weird white patches/discoloration of his scales along his body. He eats normally, swims normally, very active, loves watching me in my room. His water is 75-80 degrees F and there is a filter. I use water conditioner with tap water and just changed 1/3 of the water (I feared maybe ammonia levels were too high since the tank has not yet cycled). I have only had him in this tank for about a week, and I worry that he might have some disease, yet all of the symptoms I look up just do not match my fish. I'm hoping someone can come up with an answer, as I am new to this and want him to be happy and healthy! He means a lot to me!
Here are some pics:
The darker one concerns me more, it is on the side where the patch is bigger (although it is harder to see because his fin kinda blocks it). The discoloration has been there awhile and he shows no signs of scratching/bloating/etc, but the side on the darker picture does appear to have a small bump.
Thanks for any help in advance!
