My one boy (the one in my avatar keeps losin colour. I know that sounds a little odd.
I recently moved him into a new tank, which is divided and he can see my other male. his habitat is very similar to his old one.
He suddenly goes pale for no reason and looks as if he has "stripes" on him. Eventually he goes back to his full colour.
Any ideas why this is happening? he is eating VERY well, not really flaring at the other Betta and is swimming as usual because he is always very active.
Im going to try take a before and after picture to show what i mean.
Could it be stress?
