It was a whitetip..
It died...and i know why..i think
My Theory
I have a glass canopy and eveytime i do a water change, i clean BOATH sides with windex...and water would splash up to the glass and all and i guess wash it and drip down with windex in it...
I know this cause of when i checked the filters, the tip of my sponges had oil colored water floating, and there was white and blueish dryed up stuff on the top of the sponge where water dosnt touch it...
