I run chaeto, grape, mangroves, and fern in the fuge 24/7 light. I agree with the rubble on pods, the more the better. If you don't like the rubble you can hide it behind the rock work, but it is important for heavy pod production. One mandarin in a 100 gallon or more tank should do well, providing you don't have a bunch of other pod eating things in there competing with it. You can also get mandarins to eat brineshrimp by feeding live brine and slowly converting to frozen brine shrimp. Good luck, and happy reefing.
