No, the coral doesnt count for your bioload. Some of them actually help by filtering your water, like clams. I know those aren't corals but it was just an example.
I agree with everyone on waiting for your mandarin. From what your info says, it says that you already have 55lbs of LR
along with the 55 lbs that you're curing? Or do you just have the 55lbs? Either way everyone is right about it needing a mature system. You have the right idea on waiting until some time next year. However, in that time I would get a sump and get some rubble like they said to give the pods
a safe place to breed free from preditors. It is well worth it if you really want one in a tank that small. I have had two dwarf angels in my tank and both nipped at corals. I had a flame angel and a bicolor angel. Its just a 50/50 chance like Stripes said. I wont put another one in my tank because I had to tear my tank apart 3 times to get that bicolor out. I was so mad at the end I swore I wouldnt ever get another. Now my emerald crab is picking at my leathers! Just research your fish thoroughly and add them SLOWLY. HTH
