dont be so harsh on ur self.. trust me when they open up they probabaly wont look as nice as the picture.. u also got to consider those guys are running sick lighting and stuff..
but 100% when they do open up, they will look VERY nice.. and will get more color in them as soon as they get used 2 the tank..
1 tip i can give you with zoo's is do not place them high up in ur tank.. my frist set i got i had them towrds the top cuz i figured WOW COOL THEYL BE HIGHER AND BRIGHTER SINCE THERE CLOSER TO THE LIGHT
WRONG! I did not notice this until i broke a peaice of the rock it was on and put it on the bottom and i was tripping out how the bottom ones were MUCH birghter then the ones closer to the light, i moved them and to my suprise.. WOW!
even somtimes i have shadows in my tank from my rock scaping and the areas that have shadows and there are zoos seem to be glowing brighter then the ones that are out in the open...
hope that helps. and trust me, they will look good.
