I’d get rid of the Diamond “Watchman” Goby (This is Valenciennes puellaris and it’s what I would say a trap in the goby world). If you’ve never kept sand sifting gobies these are a bad one to try first, they constantly feed from the sand bed and most of not all of the nutrients they get will come from there. They need Atleast a 3” deep sand bed if not 5” and it needs to be mature by Atleast 2 years if not 4 or 5. These can rid a new sandbed of any life.
If you want a sand sifting goby that’s isn’t too hard to own, look into the Koumansetta or Amblygobius genera. They’re much easier to keep however they do still need Atleast a 2” deep sandbed.
If you want a flasher wrasse, I’d recommend getting 2 males of different species so they can then display to eachother which will cause them to flash more. The Melanurus Wrasse will get rather big and active however if you don’t mind that then it should be alright. These will need a deep but fine sandbed so they can’t tear their scales when they dive into it. Personally, I’d also try get a few more Halichoeres wrasses along with some other Cirrhilabrus and maybe Pseudojuloides however I’m biased when it comes to wrasses.
The rest are alright, however you can’t get the Yellow Eye Kole anymore as Hawaii has shut down. You can collect them yourself but you can’t get them from the LFS. A good alternative is the Blue Eye “Kole” or Twin Spot Bristletooth Tang, Ctenochaetus binotatus. These go through many pattern changes in a day and they are the perfect cleaner, mine will be constantly grazing the rock and sand making sure to get every piece of algae, even grazes on the glass when film algae grows.
