Is there a blue-enhancing food?

[RogueDiscus]

I'm careful to avoid what I've read are red enhancers with my blues, but was wondering if there's a food that specifically brings out the blue.

Blues in discus work by a slightly different mechanism than reds.The only one I have seen in literature that appears to enhance blues is spirulina ...but theres a trade off there as spirulina algae also enhances orange.

Hth,

I would work on different lighting to get the blues out. Jeff

Sera does make a pellet for blue discus but I've never tried it

Testosterone...?

The Sera has spirulina. I've used it but can't really say I noticed a difference with it.
