changing colors???

[kevinoh33]

My red male betta fish has 2 or three streaks of blue that wasn't there before. could he possibly be changing colors?

Yes, they definatly change color! It's not really that they're changing though, it's more like "brightening". Both my male and female bettas change depending on their mood, or when they see one another. After only 30 seconds of being together last night, my female is still bright purple, compared to her usual brownish/blue tint. Their color will be brightest when they're at their best. Good food and lighting, as well as a large enough home, will keep them looking best.

They change colour depending on mood and health but also temperature. A while bac my blue betta tured quite red when i increased the teperature.

just based on the desrcption i would either say hes settling down and his colors are changing

or

if they're vertical stripes he may be a little stressed from a recent water change or something.
