I also assume that I mean Colombian BI and not a "true" red tail BC. But to be honest, I am not sure. It sounds like the first one makes more sense, but he DID tell me that with her mix that her red tail would only get brighter as she ages, not dull out. That leads me to think BC?
We have a 55 gallon tank for her for right now. I realize she won't grow instantly and we will have time to find or make a bigger enclosure for her, just wanted to be prepared...
There is so little information available on the mix.
