Hey all!! About to upgrade from a 60 cube to a 4ft 75 Gallon, since I prefer the 4ft footprint. I currently have 2 clownfish, 2 bangaii cardinals, a purple firefish, 2 urchins, and a coral banded shrimp. It is a mixed reef tank (feather dusters/euphylia/anemones/softies) With upgrading to the 75 I’d like to know if I would be able to add a marine betta and/or a bristle tooth tang? How many more fish could I add to the system and what would a final stocking list look like?
