white tile

i just put in some white tile...what would be a good backround for that? should i do black, blue, white...i would like the fish to "be seen"...my rays already lokk kick-*** on the tile...even my wife who thinks fish are a waste of money said the tank looks good

ok fine....i take some pics...lol.....i didn't cut the back tile yet as i wanted to see if i liked it or not first, i may leave it and get a longer tube for the fx5 to get a "under gravel syphon" affect with the gaps between the tile....if i don't do that i will cut them to lay flat and then use some smaller pices to tighten them up...

pics will be with a camera phone, my good camera is broke

these are day pics and with a camera phone so ya....i was thinking black for the background, but the wife likes blue so i figured i would ask you guys to get a majority vote...and i could be like "they told me to do it...if you want to be mad be mad at them...lol" anyway here are the pics...

also any thoughts on what the female is at the end? she has a super long tail...she is longer then my bigger male retic with a full tail...she is about an inch smaller disc wise then that male...
