I consider myself a beginner at saltwater and even I know you surely do not put two royal gramas in the same tank. One is asking for serious problem.

I also think recommending any coral to a beginner is a serious mistake. One must understand water quality and must make sure their water is perfectly stable before introducing corals.

My 55 startout consisted of 2 McClosker Flasher Wrasse, 1 Ocellaris Clown and 1 Royal Gramma. I also have one Mexican Turbo snail. This tank ran for 2 weeks with nothing but live rock until the 1st fish (clown) was introduced.

Agreed. Nice try but again, bad recommendations. First of all, besides Damsels with Grammas being a bad combo, 2 Grammas in a 55gal??? Unless they are a mated pair, absolutely not!
Recommending Ostracion meleagris is just plain irresponsible. This fish, when stressed, will expel a toxin so potent it will wipe out everything in the tank.
