G’morning

I have a two YO male Betta in a 10 G planted tank.
The substrate is mineralized soil with plain sand on top.
I couldn’t find any dolomite so I used crushed coral and muriate of potash under the mineralized soil.
I have DIY CO2 and the ph is 6.8.
When I first bought the betta, he was a dark blue with white tips on his ventral fins.
He has been in this tank for six months. Now the tip of his tail fin is turning red and white.
It is nice looking, no fin rot or fungus. He’s happym I have a small mirror on the tank, and he’s constantly flaring his gills at it.
Is it common for a betta to change color after a long time
Just curious.

Yes, very common. I had a betta change several shades and loose his iridescence after a few years.
I just thought i would point out that the life span of a betta isnt all that long. If you're getting a few years out them you're doing great! So its possible that a change in color, especially if its a darkening or losing iridescence, is an old age related thing.

Thanx for the replies.
I know he's getting old, so am I.
Hope I last longer than he does.
