Acropora Polyps - Color Up?

mrg02d · 11/02/2018, 09:34 AM

I’ve noticed that several of my acroporas have white/clear polyps in my tank, but pictured online with different colors. Examples:

Pink Floyd has red polyps, mine are white. CB Maleficent has red polyps, mine are white. WWC pink passion has red polyps, mine are white.

Do polyps also color up? Or, do they change as the frag grows into a colony? My frags are encrusting and the new polyps are also clear/white. The rest of the corals have their characteristic colors.

What's your lighting?

I have two hydra26hd over the tank. Corals are getting between 300-400 par, mostly blue light.

Try taking a pic of the frag and bumping up the saturation on your picture really high. Boom! Instant colored polyps. That's what most vendors do. Lol.

But in all seriousness, sometimes it depends how big the frag is, because yes, sometimes the new coral axial polyps are not very saturated, but as the coral grows, the older polyps become a deeper color. Without a pic it's kind of hard to see what's going on.

Put an orange gel filter on your camera and take a pic. I bet it matches the desired colors your looking for...

I was suspecting that these just need to grow out before the polyps gained some color, but noticed that others in the tank have color. My orange passion has orange polyps. Oregon tort has intense blue polyps. Walt Disney has yellow polyps. Acid trip millepora has green polyps. New growth polyps in these all match the existing frags polyps, which has stumped me. I wonder if the frags with no color polyps are getting too much light? Could polyps bleach with the rest of the frag staying healthy?

Or, could a water chemistry problem be the answer?
