Well it does help to confirm my suspicion. It was the only thing I could come up with as far as a change goes that would effect him and only him. I guess that means I can't replace him then.
Since the mandarin does eat frozen and I now have an awesome fuge I may give it another try but not for a while at least. I want to be sure the fuge is fully established. If I am still seeing tons of pods with the mandarin I may give it a 2nd go since the entire system is actually about 180g if you count both tanks, the sump, and the fuge.
