I got a male betta 2 months ago. They told me he was roughly 4 months old. He was originally 2 coloured --> royal blue on his body and white on his tails and fins... with clear demarcation of the 2 colours
I noticed the blue "seeping" slowly into the whitethe last couple weeks, but his body colour so now his white tails and fins have blue streaks on them.
Last week his blue was looking a little bit neon green/blue- ish but still bright and everything... and then literally in 1 day I noticed some of his blue streaks on the fins are turning back to royal blue again...
Is this normal?
