Since I bought my 60 gallon, I have been cruising Foster and Smith and trying to plan out my future fish purchases. My 29 gallon tank will have the following fish before I upgrade: Coral Beauty, Starry Blenny, 2x Black Ocellaris Clowns. These fish will be transferred to the 60 gallon when it is complete. I want to keep at least one small tang in the 60, but I see the smallest need a minimum of 70g. I was wondering if it would be irresponsible to keep a tang in a 60 (57.5) gallon aquarium. I don't NEED the tang, and would rather be viewed as a responsible reefer than have ALL of the fish I want. Opinions/Advice would be appreciated.
