Just curious to find out if changing colors on betas are normal? I noticed today, that my betas tail is turning pink,and he has a pink spot on his side.
Near the tail, so im curious to find out, if there is something wrong with him that Im unaware about, or if this stage is normal? I just saw the pink in him just moments ago, i dont think the pink was there yesterday

He still seems to be very happy, with a small bubble nest still, I clean the tank as often as i can, and hes still a nosey lil thing.He basically still does is daily stuff he normally does.
