I have been checking out the red jewels in my lfs and am considering adding one or some to my african tank. I was worried that they stay too small for my current stock but was reading today that they are highly aggressive and can hang with much larger fish. The fish that he would be going in with would be a 16" pike cichlid, 5" demasoni, 6" acei, 6" rusty, 6" yellow lab, 15" pleco and a large male convict. By the time I add another fish I should have a 90 or 120 gallon tank with some caves. What are the chances that a red jewel or a couple of red jewels would survive and thrive? I know my pike would try to eat them even if they are full grown because he tries to eat my demasoni on occasion but would they be tough enough to be alright. The only fish with similar coloration in the tank to a red jewel would be my rusty but there is still a significant color difference. Just wondered if anyone had experience with them.
