NEON galaxia turned brown

[uglyamericanV1]

i took a neon galaxia from my 75 gal tank, with 220 watts t-5 and placed it into a 100 gallon with over 400 watts halide/pc and they turned (overnight it looked like) a (to be honest, nice) brown.....

much better looking when neon, just wanted to know if there is something i did to do that, or what can be done to fix it.

water = 1.025
ammonia 0
nitrite 0
nitrate 0

(note that the 75 gallon was 20 ppm nitrate but otherwise the same)

I have read that they will react to changes in lighting by adjusting coloration. It may be the spectrum or just the watts. You could make sure the spectrum of both bulbs is the same. Just about every place that sells them has a note about color change.
I would like to know how this turns out, Could you post a pick?
How was the placement before, how is it placed now?

it actually has been in three diffrent tanks.....
mother was in a 30 gallon with 130 watts pc on the bottom with mod flow from that was made 4 frags
three frags are in the 75 gallon with heavy flow (two at bottom one right at the top) with 220 watts t5
and the other is at my lfs...........at mid level, low flow with the halides............
