That will be a comfortably full tank and the SD's you picked are really awesome looking and will add a ton of movement in the upper areas of the tank. But be prepared they are aggressive feeders. I used to have to close the lid as soon as I dropped the pellets in otherwise a tidal wave of water came my day as they darted up for food. They eat fast too so I suggest to do a mix of floaters and sinkers so that all the fish can get food. They are greedy so I put some large floating pellets in which they always went for and it kept them occupied for a bit trying to crunch those down and allowed the other fish to eat the medium to small sized pellets.
