Not sure...have you already gotten a pic of what the eggs look like so you know what to look for?
You can look here if you want.... [ame="http://www.youtube.com/watch?v=mrzmP_2b8uw"]YouTube- Clownfish 8/13/2010 Day 1[/ame] mine were laying on the back of a large statue when in the DT, finally found that out and moved them.
They have changed their location since being added to the biocube (because I moved the rock they initially laid on) They now have laid on the back wall. Is there a way you could move a rock or two in your tank, this may disorient them, then they will locate a new spot and you can see where they stay near the most- that will be your spot. Or have you already found the spot?
