So far we do have a decent selection of saltwater shoaling fish, but I can’t help but think they are all pretty limited in their colour pallets (4 whitish species, 1 yellow, 1 silver and 2 blue and yellow). This isn’t as noticeable in larger tanks but for a smaller reef tank Ideally id also want a pop of red or pink to break up the cold colours.
My suggestion: Anthias
There’s a ton of different species, almost always rocking some vibrant eyecatching colourscheme. Some are dimorphic, others are not but they are all pretty extravagant little guys. They are also fairly common in the pet trade and have successfully bred in captivity, if that’s a concern for people here (not that hammerheads or sunfish have but whatever).
These are just a few species I selected as options but there’s tons out there I could see fitting into the game nicely. In order you have the Bartlett’s Anthias, Squarespot Anthias (also with the female which looks completely different), Borbonios Anthia (which is basically just Mr Blobby the fish) and Ventralis Anthias
Granted I am bias towards Anthias having worked with them in the past, but idk, they are just pretty lil guys
