Mixing tap and RO is a solid plan if your tap's too hard. Just remember to condition it. What's your tap pH and KH?

Crushed coral works, but you'll need to monitor KH too. If your water's too soft, the pH will keep crashing. Test your KH and GH—if they're below 3 dKH, consider adding a remineralizer like Seachem Equilibrium.

I'm not that familiar with smaller tanks, but I think a firstideflow goby might work well in a tank that size, probably.

I'll check out the orchid dottyback, how do they get along with royal grammas though?

I'm concerned a yellow tang would outgrow my 55 gallon tank, aren't they known to get pretty big?

oops did i forget to post firtideflow . id love to get a shrimp/goby pair but how do i do it - buy them separate or together as a pair?

I'd love to get one, but I've never come across an orchid dottyback in a US shop.

yeah, those are definitely on my list, any other peaceful fish you'd recommend? i've got plenty of space in my tank, so i'm open to suggestions

I've got a 55-gallon tank with 57 pounds of liverock, which is home to three hermit crabs, a bunch of snails, a pink tip anemone that came on the live rock, a sand sifter goby, a tomato clown fish, a sixline wrasse, some orange coflake polyps, and purple star polyps. I'm looking to add some more ...

For a more structured look, consider Microsorum pteropus. It's similar to Java Fern but can handle slightly higher salinity. Just keep the water params stable.
