No. They are not a sand sifting Goby. I think you may have confused it with the Diamond Watchman which belongs to the genus Valencianna (is that how it’s spelled?). The Flame Angel, or a Coral Beauty, or any of the 4” dwarf angels IMO can go into a tank of your size as long as it’s 3-foot long but IMO long term a 4-foot tank would be even more ideal. The Multibar is a difficult fish, many refuse to eat and wither away. I wouldn’t recommend it over a Flame or Coral Beauty or any of the pygmy angels.

My tank is redsea reefer 250 and it is 36” long.

Then a Coral Beauty or a Flame could work, IMO.

For angelfish, how about flame angelfish or multibar?

Yellow watchmen moves sand around and build sand dune everywhere? If that’s the case, I prefer not having it. I don’t like to see sand dunes everywhere’s. Any alternative that doesn’t build sand dunes?

Multibars are notoriously difficult and need a well established tank too. So maybe one for a year or 2 down the line
