Unknown Water Condition

i was looking at my tank today and noticed that on the top there seems to be swirls of iridescent colors. it looks similar to when you see oil on the street (the colors of the swirl) should i be worried or not? any body else notice it on their tanks?

Typically it is either the oils from your skin if you've been in there a lot, and also a lot of foods are fatty and leave a sheen on the surface. I've seen it in my tank before and not had any problems, but if you're seeing any signs of stress just change out a decent amount of water. Sounds pretty normal though.

Thanks man that's a load off my mind for now.

Try agitating the water surface more to break it up.

Spraybar is good for it, or even just run an airstone. Anything at all which will disrupt the surface will help. I had this on my 100ltr tank then plugged an airstone in and it's been fine since.
