Looks good so far. How big of a snowflake are you going to get? Are you going to get a hang on the back wet/dry or the one that goes under the tank? Get a bak pak skimmer. Very dependable and fairly quiet. Buy it online if it is possible. You have room for 1-2 more fish. How about a big clown fish? Or a trigger? Maybe a wrasse? Blue, Yellow or a Kole tang? Good luck.....
