CRS white turning dull
Hey guys I'm new here! I have some SSS CRS and their white colors have turned a bit dull over the past month that I've had them. It's similar to a yellowing white color, but their tails maintained the crystal white color. They're 1/2 to 1 inch long some still not mature enough to determine whether they're male or female. They were crystal white when I received them in the mail.
I've done a water test and here are my results:
and food I feed them is Shrimp king complete, SK 5 leaf mix, SK protein, SK mineral and SK snow pops.
Do you think the gh is the culprit or genetics? Any feedback would be appreciated thanks!
