I'm not going to comment on the size of tank, but I would be concerned about the competition for food. You mandarin in the 20g has no competitors for pods, I'm assuming. With you water volume, I would, at the very least, be supplementing with reef pods regularly (meaning at least ne bottle every 2 months). I have a 125 with a 55 sump/fuge and I put a bottle of pods in at every other month and I still don't see a lot of pods in my system. I have Leopard Wrasses as well as the mandarin, so the pod population is being hammered.
