Earlier this year, I purchased an hatchling "blacktail" from a local shop around here (not a breeder). It never had a jet black tail to begin with, but now is loosing its color distinction between its tail and body. It's starting to look more like a Unicolor. Does anyone have experiences with this color change? Could it have been a unicolor all along? Do Uni's hatch out with darker tails?
Any advice would be appreciated!
