Acan turning green?

[Notsolostfish]

What does it means when acan turning green. My orange one turning green. Weird

 

[VintageReefer]

I don’t see any green?

But I know the phenomenon.

Many many people experience this with wild caught acan. Usually sold as rainbow acans but not always. Most of these either turn all red or all green.

I spent a lot of money on acans from a well known vendor and they were red and orange and yellow mixed together. And in a few months they were plain red acans.

Try and talk to seller and only buy aquacultured or ones grown out and fragged by the seller. These have most success in retaining color. Also low light seems to work better for most people

This was orange with a hint of purple. I always figured it was a spectrum thing as my sand bed hits 250+.

Like too much light?

I don’t think it’s spectrum. The two biggest reasons for acans morphing to a solid color are coral origin and being wild caught, or, too much light.

I learned this and tried again and my acans have not only retained color, more coloration has come out. I have them in 80-100 par

Well you got me as this one came from the same person " aquacultured" and has been subject to the same light, flow, nutrients, ect. and has never changed.

That one is on the sandbed. How high is the other one

Sand bed also

What light spectrum do you use? My nitrates are around 10 to 15ppm and phosphate at 0.07ppm and PAR of 80 but still my acans turned green or orange. I think it maybe to do with spectrum hence my question

 

[VintageReefer]

I feel now it’s spectrum and par.
I run full blue/uv. I don’t use white too often

Here’s updated pics of the above trio

Middle one is nearly dead. It turns out I had a fish eating it when I wasn’t around. I captured the fish before he moved onto others

The orange one has become more vibrant and has more accents of yellow

And the one with the yellow ring has become a little more pale/purple but the yellow ring is retained. I moved him into an actual shaded spot a few days ago to see what happens

The teal/orange one is mostly unchanged. Maybe the orange became slightly pinker I’m not sure. I moved it to a different tank so the lighting isn’t the same as it was before

I’ll tell you this. I have a lot of bright lps corals, and these rainbow acans are my only corals this happens to, and I’m not buying acans again lol

Yeah, my torches, hammers and scoly and Zoa and frogspawn and favia haven’t change at all. Only the so called rainbow acans turned green or orange with a tiny ring of light blue. I still have a teal and red acan. Going to increase the blue light at 453nm and dial down the hours on the white to see if it will keep colors. Getting tired of acans/micromussas losing all their bright colors and turning orange or green or brown. Corals are healthy and growing heads though

yea i hear ya. I use reefbreeders photon v2. I don’t know the blues spectrum and am too lazy at the moment to look it up. I use the dark blue, light blue, and uv channels at 45%. I leave green, red, and white off. It’s around 100 par in my sandbed.

My “non rainbow” regular acans in another system are bullet proof. Several years, algae outbreaks, led brand changes, neglect lol. They are happy and open everyday and never changed colors once

I change my statement in the prior post. I’m never buying rainbow acans again. If I see nice green or red or two color ones, I’d consider. But these expensive fire and rainbow ones…are a bait and switch lol

Ok here’s my test piece…
Ignore the trash paly next to it, the teal/orange/purple scoly and the bleeding apple are going to be the control subjects to see if my new light regime will keep the acans from changing color. I’ll update with an all blue light only later
