After listening this months meeting I couldn't help think perhaps I found the explanation to my disappearing clown. I have a pair of false percs in a 120 reef and every once in a while the male disappears. I always find him in the back corner of the tank in the rock work. He will come back after a few days. The speaker said the male would guard the eggs. So.. if thats the case then awesome! but the rock work can't really be torn down there. I've now added a little pot back there, but is there any way to convince them that the pot is better than the rock for next time? Or will I have to mix up all the rock work and make the pot the best choice? Any advice would be much appreciated.
