What ta do?

[LionFish47]

I've kept multiple aquariums before, but on a decision to restart on everything but the tank itself, I'm torn between a FOWLER tank or a community tank. The tank is all set up, a clean up crew, rocks, and the previous sump, tank, lights etc. My local fish store suggested that I add a fish or two while waiting to add the real livestock. Without much future thought, I added a Blue Velvet Damselfish, as he was priced low and would spice up the aquarium until further fish could be added. I got the fish a few days ago, and I'm now beginning to lean towards the community reef. If I go with community, how soon should I add the other livestock before the Blue Velvet Damselfish becomes territorial, or by putting him in first, have I offset the balance beyond repair with out getting him out? BTW: My tank is a 75 gallon tall and would probably be more suitable for a community tank anyways, the tank is to small for any good predator fish.

Thanks in advance

Blue velvet damsel is going to be aggressive regardless. It may be best to get him out before there are any real issues.
