I'm in the planning process of my first aquarium fowlr
. It will be a 90gallon with sump and fuge. When I checked the stock calculator it said I could have 18inches of fish minus the tail. I'd like to keep a pair of True Percs, a yellow watchman goby, and a school(3-7) b/g chromis. If they will all fit what would be the best order to add them to the tank as to not cause any territorial issues.
