46 gallon stock list

Your stocking list sounds good. I really can't see any glaring issues with it. Just be careful with the Christmas Wrasse if you get one.. I have seen several wrasses that look similar labeled as a Christmas Wrasse and some of the mislabeled ones are mean, fish only types, and get really big. Check out Google Images for Christmas Wrasse and you will see what I am talking about.

I have always loved Tangs, great reef fish IMO. Your tank is little small for a tangs though. For a 55gal or less the dwarf Angels (Coral Beauty) that you already have is a nice center fish. If you are planning on a reef (and I assume SPS corals) remember you must stock lightly to have a successfull reef tank.

You may have to fine this out the hard way, but I have NEVER had much sucess with chromis. They always kill each other till I only have one large one!!!! This was in my 120gal. It did not make a difference if I had 3,5 or 7. eventually I had only one!!!

3 in a 46G may be pushing it.. here is a picture from my old house mates tank/Chromis, standard 75G.. started with 2 babies... 5 years later had 2 big fat adults.. perfect fish the entire time. I think tangs are great reef fish as well, as long as you have a suitable tank for them (120G+ for all except the bristletooth family). I see way to many people putting yellow tangs in tanks less than 100G and it is rarely a happy tang (90% of yellow tangs I see in tanks under 100G have HLLE disease), although there are exceptions.
