I setup my tank primarily as a Angelfish display tank. Currently I have three with expansion planned, however two of them paired off a couple weeks ago. Today I looked up from my computer to see them spawning! Go baby go!
This video was taken during the egg laying process. Notices that the female (silver) runs her body along the glass laying eggs, then the male (marble) comes along behind her and fertilizes the little eggies.
Tip: Fullscreen the video. It is HD
