final addition to my 55 gal-Boeseman's Rainbows?

[Sambo7475]

I really like the look of the Boeseman's rainbows, and after careful consideration, I think they will fit nicely in my 55 gallon. I want to add a school of 5, AqAdvisor says I will be 111% stocked, though, and when the corys and silver dollars are full grown, it will be 126%. My filtration is adequate, and I do 25% weekly water changes.

Currently I have:
12x serpae tetra
2x Silver Dollars
3x Albino Corys
1x 3 year old common pleco (about 4 inches in length-hasn't grown in about 1 year)
1x Dojo loach (his 2 buddies died, and now he shoals with the pleco)

Any input is appreciated.
