hi! i am going to stock my 28 gallon nano with approximately the same critters as you did, just in a different order. my turbo, peppermint shrimp and some soil sifter snails were first. a week later, i noticed some hair algae matting up on some corals, so the lfs told me to get three banded trocus as they will eat this stuff. i got three of them.. by the the way, during all of this, i did add a tiny green star polyp for the back of the tank (hope it will someday cover the back), a small zoanthid, which has both green and red polyps, and an orange/red mushroom. in doing my studying, i knew to put in the meeker, quieter fish first, which will be the royal gramma and a couple more corals. a week later, a banggai cardinal fish, with a couple of corals, a week later, hopefully a long finned fairy wrasse and corals and last, the clownfish (i want two). i will also take the lfs advise if i'm stocking too heavily and will make adjustments then. the clowns have a bit of a temper when other fish take their spot, so you would have stocked them last. you may get green water, an algae bloom, which was the hardest thing we've dealt with, but that's over so now, it's my turn to stock. at my lfs, they captive raise almost all their animals, and that is a major point for me, so i drive almost an hour in heavy traffic to get to them. your tank looks very nice and you probably have not over stocked too heavily. my only concern is putting the clowns before the gramma. she may start to hide more, so be sure she gets food. i'd really stick with all soft corals because our tanks are so small, that we don't need Stonies stinging them to death if they grow closer, which they will in a small tank. anyway, that's my story and i'll stick to it. : ) i hope all goes well with you're tank. i read solidly for 4 months to be prepared to do this, but it all came down to a trustworthy lfs and these forums. keep reading and have fun!
