Just thought I would share a photo of my seahorses from Golds.
These three started out mostly black like all the others in the upper tank.
The color on seahorses have a lot to do with your lighting and choice of backgrounds and tank decorations.
Conversely, I have seen very bright and colorful seahorses fade ou tto black in some tanks, imagine bringing home a beautiful red or yellow horse just to watch it faded out once you get it home.

It took about 3 days for the seahorses to adapt to the new tank and start changing colors. They also change colors while breeding and when stressed. Being such a slow moving fish - their primary defense is camoflage - so it makes sense the more colorful the display the more colorful the seahorses.

I also noticed this way back when I had dwarf seahorses. They were all white when I bought them - within two weeks I only had 2 wjite ones left, the rest were greens, yellows and shades of brown/red.
