Omigawsh, I`ve been told a few times about Betta Fish marbeling but, what does that mean? Is he going to die? ;.; I dont want Blue to die!!!! I dont even know how old he is ): How do you find out? *cries*
Thanks Fleet!!!A betta is usually around six months to a year old in a petstore, but don't worry! They can live up to five years with proper care. You might see some red wash as he ages, but it's okay.
Marbelling is a type of gene, not any indication that Blue will die. It's one of my personal favourite colours
