WTB Pair of Blue Angelfish

I am looking for a pair of blue angelfish, they don't need to be perfect, the primary need is for two mated angelfish that get along and are "pretty and shiny". They will be going into a 20 high tank tank for someone who had to give up their cat to move in with their adult child (who doesn't like cats but is ok with fish). I can pick up at the February meeting. The cat was a calico so I might be able to convicne her to take a pair with orange/black Koi markings also. Thanks
