green birds nest

mikey77 · 04/15/2007, 06:36 PM

is it common for green birds nest to brown out if the lighting it's kept under is too bright? I've been keeping one in my tank for a couple months and while there has been noticeable growth and great p.e., the color of the polyps has really turned dull. currently it is about 18" from a 250 watt metal halide. would moving it to a lower level in the aquarium be a good first step? anyone have experience with this? thanks for any help.

i probably should note that there are other sps in the tank that are thriving and colorful. all chemical paramaters are in check.

i`ve got one in my 90 gallon sps! an it sits at the botom of the tank about a half a meter(50cm) under a 150W hqi. and the collor and pe is great!

It has been my experience that green bird's nest corals thrive under lower metal halide light, and are not as colorful under more intense light.

Here is a picture of my green birdsnest under 175 watt MH lamps (with corals in the middle or upper part of tank):

This is what the birdsnest looks like under 400 watt MH (sitting at the bottom of the tank):

Mine have a rich green polyp color on the bottom of my 20" tank under 6 T5 bulbs.

Mine sits about 6in below water level. I have 2-250w MH's about 9in above that...grn as can be and growing like made....

Older shot...much larger now!

nice

twon8 · 04/16/2007, 03:02 PM

mine is about a foot under a 400w 20k, and it has great color

We get much better color (green) in the wifes T5 tank then in my sps hallide tank.

Oldude · 04/16/2007, 04:09 PM

What kelvin are the lights? This will affect the color you see the coral as and why the same thing looks different under the T5's.

2crazyreefers · 04/16/2007, 07:05 PM

I run 10 K on both ends and 13 K in the middle with same results.

Oldude · 04/16/2007, 11:12 PM

do the T5's have actinics as well? Many lights say they are whatever K, but will still vary in color temp with manufacturers.

That is a sweet piece that to me more resembles a stylophora than seriatopora. I like it.

mehmet · 04/17/2007, 02:26 AM

they are seriatapora caliendrum

mine is doing good under t5's with no current

makoJ · 04/17/2007, 10:22 AM

mine likes high light about 8" under 400w 10k

2crazyreefers · 04/17/2007, 07:15 PM

Mine under the T5 looks just like makoj does. Definately not like this under my halides with actinics.
