I am not an expert at Betta diseases but i KINDA think that it is velvet???
Betta has white cottony like patches on its body or head. He may be less active, may have stopped eating, fins may be clumped, color may be pale. ( fungal infection)

Betta has white dots (looks like he was sprinkled with salt) all over his body and head, even eyes. He may be less active, may have stopped eating, fins may be clumped. he may also be darting and scratching against rocks, plants and whatever else he can find. (ick)

Velvet is hard to spot, but can be best spotted with a flashlight. Shine the light on the betta’s body: if it looks like it is covered with a fine gold or rust mist, then it has velvet. A betta with velvet will act sick, so look for clamped fins, scratching against rocks/gravel/tank, loss of appetite, loss of color etc... (Velvet)

Hope this helps!

Waaaaaaaa Sorry i am watching a sad, sad movie about humpback whales dieing ;(

I shined a flashlight on him and there are no signs of ick or any cottony patches. His scales are smooth and flat. When I got him about a month ago his body was solid white and his fins were black and turquoise. He has been changing a lot lately and is getting speckles of blue and yellow on his body. His fins are now royal blue with a few stripes of yellow, green and red. I am hoping whatever this is has to do with his color change and not illness. I did a 50% water change today and added Stress Coat instead of Prime. He is eating and acting normally and is busy working on his bubble nest. I guess I will just keep a close eye on him and see what happens. Thanks.

The patch on the side looks rather like he's lost some scales. The good news is he looks healthy. The other possibility is you have a marble, meaning he will change colour over time. Does he seem healthy other than the colour change?

 

[Saphirra]

I am pretty sure he is a marble. He is getting color in on his body and his tail color is getting more and more colors in it. He is acting perfectly normal and eating like a pig as always. I think he may have actually rubbed against the heater. Long story but I had to turn up my filter flow yesterday because my water was cloudy and he wasn't the biggest fan of the current. I think he may have slept by the heater instead of his normal spot and rubbed against it. I'll keep and eye on him but he seems to be feeling fine. Thanks.

P.S. I turned the flow back down today.

HE is a handsome boy. It may or may not be missing scales, but it is likely marbling, in which case he is just fine. Sounds like you have things well in hand. If you notice anything else then you have more cause to be concerned
