Nice looking fish. I find golden base a bit harder and have to be patient when it comes to getting full potential in coloration. It's a lot to do with their genetics. I agree with most comments. Just feed good healthy food not too high in protein, maintain good healthy water and their environment the FH will slowly show it's full potential. Here's a couple of pics of my golden base and my F2. Genetics plays a huge role. The golden base is at 5 inches and the F2 at 4 inches.
