I have noticed indevidual personalities in several of my fishes. The Bettas were speacial though. Always sweet and thriving. They always wanted human interaction but it was always excitement over maybe it's dinner time again. They are always hungry and it's hard to say no more food. They are gorgious and will always hold a speacial place. It's very difficult around here to find healthy ones too. I know of only one place I trust to get them. I'm waiting to get another one. Replacement issues. Also I want to make sure the chemistry don't go bad (dought it will). Then to find the right personality. Wittaker just popped out and it was love at first sight. Plus I'd never seen a Betta w/ that color or pattern. Beautiful. I could not upload photos on here but I was able to upload one on a reef forum.
