No, mainly because if the angels decide to fight back, and defeat the jewel, the Jewel's end up killing them. Jewel cichlids do not like to lose, which is very bad. I'd stay away from jewels and angels in the same tanks, unless you have a divider.
thats what i thought, just checking cause cdf has all those cichlids he needs to get rid of and has a jewel and i remember hearing they like a low pH thought i might ask if they would work.
