Looks like they will be a good match. I have a small group of cardinals and my other tangs are about the same size. I am in South Austin... let me google where you are at
.
I have lots of purple digi as my main coral is HUGE and needs a trimming. I will be home tomorrow evening after 6:00 if anyone wants to stop by. Please send me a PM of what time works for you.

Several pieces have broken off and have been relocated to a zip-loc bag. Free to a new home. They are all ready to go ASAP! Please take them as I am out of room in my frag tank.
Brooks, I have a 250w SE Reeflux 10k that I pulled, it is about 8 months old - you are welcome to have it if you want to see if that bulb spectrum/brand will work for you.
