Hi, first time on this - I'm a little worried as my betta has a white patch on his body near his belly either side. This is the best photo I could get of him as he doesn't seem to camera friendly today.
He's just over a year old, I've noticed it for a while but it seems more white now. He is in about a 13 L tank, and I just did a full water change after being away for three weeks.
He eats normally (although he is a little fat as dad overdid his food while i was away!) and he swims around enough, although he doesn't seem as happy as usual.
That's all the information I can think of!
Helllpppp! Do I have good reason to worry or is it just old age?
