Nice, I'd love to see some pics! I did a search on here and found Yo-Hans Flamingo
, it looks like it has it. Did yours come with the spangled leaves or grow them in your tank? What's your lighting like? I'm starting to think it's an artifact of very high lighting. Yo-Han also uses a lot of light, not sure the exact amounts, but it looks like a lot. Mine is growing directly under 52 watts of '5600K' light and 10 inches of water, totaling only 10 gallons(20 high, half-full). I can't get PAR numbers, but at 5.2 watts/gallon, it's a lot. Some algae(Zooxanthellae) are know for producing light-defending proteins when exposed to high levels of light. These proteins are often a metallic white/blue, reflecting light, protecting them from excessive free radicals that are produced during photosynthesis. Of course it could easily be something different.
Time will tell, but I have a jumping off point for some experimentation.
