electric yelow lab to turn a shade of black? Colud it be frtom stress I just added some new rock work to the tank? Water is vey good condition.
thanks for the help.
No worries, it's normal for some of them to do that. Some do, some don't, it just depends on their breeding. I have yellow lab's that have never shown the black color, while there are some in a display tank at the lfs that do.
