Are there any issues with my stocking idea?

I've gone and done it again! I've gone and restarted my list of ideas!
I have a 55 gallon, and I plan to go reef at some point (I will be using RO/DI water). At least 70 lbs of base rock waits for me to assemble it into various shapes and whatnot. Sooo...

1 Blue Sapphire Damsel
1 Yellowtail Damsel
1 Bicolor Dottyback
1 Clownfish (possibly an Ocellaris of some sort)

For the Yellowtail, I've read and heard that the fish count should be odd, so there's that... I've known Damsels to be pretty mean, but I believe I've chosen the least mean of them all, and the Yellowtail might be the one from a crowded tank I know of that has more aggressive fish that scared him almost permanently into a corner.

If you could please tell me of any possible issues, that'd be great. And also, perhaps, how I should arrange my rock to reduce aggression by allowing more territory to be taken.

 

The damsels and the clown all have the possibility of being on the aggressive side. If one has been bullied in a previous tank that doesn't mean he didn't learn how to be a bully and may pass that along to other fish.

 

I'd probably be the most concerned about the blue sapphire damsel. I'd look to add the clown and any damsels last as far as stocking order goes. You may want to rearrange your rock in between additions to reduce territory battles.

 

I would be tempted to follow that plan, you already know they may tend to be on the aggressive side. My suggestion is to ask your LFS to order them and get them all young. I have done it without issue, I also ask that they remain in the shipping bag pick up same day by me.

I have kept the clowns and the yellow tail together for about a year or so, usually the clowns got too aggressive and went after the yellow tail. My tank was only a 28, so at least you have a larger tank going for you.

Really try to QT everything and monitor for a decline in water quality after introduction to the display.

 

Ok, so I was just offered instead the 2 Jewel Damsels from the tank the Yellowtail would come from. If I take those, I would again trash this idea and only keep them in the tank. And perhaps a Domino Damsel...or something as aggressive as the Jewels...?

 

Domino Clown grow to be very aggressive, one almost killed me, I kid you not.

 

LOL...I have a little Cinnamon Clown, who is king of my 65 gal, that attacks me anytime I delve into the tank. It is starting to hurt. He latches onto the backside of my fingers...ouch.

 

Seriously I was diving and needed a hold fast and my hold fast contained a Domino Damsel, going against current, BC floating above my head and a Damsel biting the crap out of my hand. Good times.
