curviceps Posted July 23, 2011 Share Posted July 23, 2011 G'day Since I moved my clown loaches to my tank with black sand, 5 out of 6 have turned very dark. There is one that remains "normal" with the orange parts contrasting well with the black parts. It has been many months now. Apart from that, they are fine. Any ideas about how to change this, apart from having to change the substrate to a light colour? Cheers Tim Link to comment Share on other sites More sharing options...
