Fun Fact
Did you know that true blue pigment is incredibly rare in nature? Most blue fish, like the Blue Betta or Blue Tang, don’t actually have blue cells! Instead, they use “structural color.” Their scales contain microscopic crystal structures called iridophores that scatter light, reflecting only the blue wavelengths back to our eyes. It is an amazing biological light show!

A “cool” name gives your fish a bit of an aura, making even a small guppy seem like a formidable ruler of its underwater kingdom.
