How To Bring Out Blues?

[Avinitlarge]

I have quite a few discus with alot of blue. They are in a Juwel Trigon 350 with 4 lights. I have modified the light units so there are 3 seseperate circuits. The the small rear light has a Marine Glo which comes on in the evening, The small front has a power glo, The large rear is a power glo and the large front is a sun Glo. The blues on the fish dont look brilliant, What would I use to bring more of the blue out??
