I was at my LFS on Black Friday and couldn't believe my eyes when I saw a solid black betta. I was afraid the store lighting was playing tricks on me but when we got home sure enough he is solid black and adorable. Mr. Friday is now home and happy as can be!!!!!!
True black Bettas are called Melanos. They are unfortunately sterile so they are indeed rare and are only found as a type of fluke of other matings. They are very beautiful and usually can NEVER be found in fish or pet stores. You are indeed a very lucky lady. I would give him a place of distinction and keep him very carefully. It is very doubtful that you will ever find another locally. I had a little black female who passed away this year and she was purchased directly from a breeder for half my right arm.
Congratulations, we will hold you to the promise of pictures. ;D We do love BABY PICTURES!!
Welcome to our community, Mr. Friday!! My Marty, Alexander & Emma bid you welcome with waving fins and much excitement.
