several months ago, I got 4 super tiny red line severums. All four of them had the red lines on their body already, though slightly faded. As three of them grew up, they kept the red lines, and they just grew brighter and more beautiful. one of them though, lost the red lines completely and just looks like a regular gold severum except for quite a bit of red in the face and fins.
Any reason why the one lost its color?
