I will be upgrading to a 400 gallon 5'x5' plywood lagoon style tank over the Christmas break. Having been in the hobby for more than a decade, I have learned to take things slowly and to carefully consider every new fish added. Currently in my 55 gallon, I only have a large 4" maroon clown, a bicolor pseudochromis, and a little yellow tang that has grown quickly from a little 1.5" guy to over 3" in the several months that I have had it. I have noticed that as it gets larger, it is getting more bold about hanging out around the maroons anemone hoard. They get along well enough, though the yellow has made a couple of empty threats with its scalpel tail. After the all have moved into the 400, I was planning on adding a hippo and powder brown of about the same size as the yellow. I've not had or heard of too many problems with yellow and hippo, but know powder browns and the yellow to some extent can be aggressive. I'm wondering if I should add the hippo first and let it settle in with the yellow, or if adding both at the same time, considering the tank size, would probably be ok? Maybe even the hippo should go first, but it will be in QT for 90 days and I kind of wanted to get the 400 occupied after it cycled. Thoughts?
