I picked up my first lovely betta Merlin in late august. He was fine up until earlier this week, when I noticed some white patches on his chest that weren't cottony. Despite that, I immediately thought it was a fungal infection and bought him the only stuff that the pet store had for this sort of thing- Bettafix.
I medicated his tank yesterday and thought that he was moving around a bit more. Before the medication he wasn't acting exactly like a sick fish would. He was still eating and moving around a bit, but he was also spending a lot more time ( I think) laying still at the top/bottom of the tank.
I did some more research on Betta sickness and found some pictures of marbled bettas and thought his chest looked kind of similar.
Here's a picture:
[sorry for the quality, he didn't like the camera lens and was moving around.]
I did change his water conditioner a couple weeks ago. I changed it back when I did a 100% water change with the medication.
Thanks for looking at him! I hope he's marbled because that would mean he's healthy, but if he is I'd feel awful for medicating him when it wasn't necessary.
