Jewel cichlids are gorgeous fish, no doubt about it - especially when they're ready to spawn. Unfortunately, that's when they get ornery and downright vicious. I'll tell you my experiences with these fish, but keep in mind,
YMMV.
Several months ago, I purchased two blue acaras, a firemouth, and a red jewel for my 58
gal. The firemouth has always been the most agressive fish in that tank. Recently, however, the jewel has taken over the tank. One night, I came home to find the firemouth beaten up and the two acaras huddling terrified in an upper corner. I removed the jewel immediately to another tank.
In December, I purchased two jewels at auction - supposedly a pair. I was hoping to put them in my 58
gal with the other jewel, firemouth, and acara. The president of my aquarium society told me that jewels can become so vicious, I might as well put all their tankmates in a blender and turn it on.. 8O But, he said that given the size of my tank and the abundance of hiding places, I might get lucky. He cautioned me to have a plan B ready in case there was aggression. I had an empty, cycled 10
gal standing by.
Well, one of the new jewels never even made it out of quarrantine - it was attacked and harassed to death by its 'mate'. So now, I have a 10
gal inhabited by two jewel cichlids that I know to be too aggressive to be placed in any community tank. I love the vibrant red and blue colors of this fish and its personality, but
IME, they belong in a species only tank.
So, to answer your question, I'd say either consider a separate jewel tank, or bring them back and add some more Africans.
