My particle affect is appearing behind my background

I created a prefab of a heart exploding the heart image appears above my background image just fine, but my particles are appearing behind the background image. The background is set to the layer background and everything in my prefab is set to UI. My background is splitting my prefab, which it shouldn’t be doing as the prefab come after the image in the heirarchy. Any idea’s? I’ve also tried creating sort layers, but that doesn’t seem to be working. Any ideas? Thanks.

Nevermind, I figured it out. The background’s render mode wasn’t set to camera space.
