I'm still sticking with my previous post. It is a trusted method that many have use and have had luck with. You are right, refugium is a more sound way to approach. I was just simply stating another method, I did not say to toss the idea of a sump. As I have bolded, you can see that I said can't get into. I did not edit this as you can check the quote in your post. Getting two in one tank even with a fuge can have a bad ending IMO
. He will need to sex them when he buys them. Two of the same sex WILL kill each other, two of a different species WILL kill each other. It is better to have just one in a tank unless you have them trained on brine. The mandarin may still topple the pod population even with a refugium. As you may have read before, it could take a 100g full of live rock to feed a mandarin properly and may still not be enough. HTH
