Great question. I have two things I would have done differently.
1. I would have added a little seed rock when I set up the tank. The dry rock is okay but I miss the diversity, the joy of seeing some little thing suddenly growing on your rock. I have a small dino problem right now but that is not the fault of the rock. It's mine. I just think the rock looks too barren.
2. I would have gone bigger. I resisted going back into reefing for a long time because I knew how much it can cost, the issues you can face, the space all of the "stuff" can take and the time it can take. Of course the enjoyment far outweighs all of that but... Anyway, I finally bought a little 15 gallon AIO that fit on a table in our living room pretty well. We really like having it there and the two firefish in it seem to love it. They are always out looking for breakfast before their light goes on and don't go to bed until lights out 13.5 hours later. They never hide and rarely go into the tunnels. The "problem" is I would really like a few more fish but they are so at home (they don't even hide when we are cleaning the rocks or glass) that I don't want to upset their happy home. 15 gallons just isn't big enough to really give room for other fish. That said, 15 gallons was my budget so 15 gallons it is.
