How long have you had Tiger Barbs? I just love mine. They are not fully grown yet. I have had them since they were very little. I have 4 Tiger Barbs, "The Indians": Cherokee, Appache, Chawktaw, & Crow. I also have 3 Green Barbs, "The Cowboys": Buffalo Bill, Billy the Kid, & Wild Bill Hickcock. They Have really brought a lot of life to my tank and I love them. I am very interested to learn anything I can about these delightful little fish.
