Fish Selectin for 8 gallon Nuvo Marine Nano

[chromakey]

Good Day:

I have two clowns in my 8 gallon nano for about one year and was thinking of replacing them with a couple of smaller fish. I was looking for smaller fish that aren't fussy eater to minimize the food waste in the tank. My daughter likes the royal gramma. I was thinking of one tail spot blenny and maybe the gramma or firefish.

Is there a pair of fish you would recommend or two or three different species?

Thanks for your time,

Michael
