I kept a mated pair of red jewels for my tank. They were semi aggressive, but not psycho samurai crazy. The baby fish that hatched were great and so animated. Most of them grew to over 1" and then i traded them in sine they were eating a jar of tetra standard flakes 9 ozs every 4 days lol. The jewels were in a tank with a blue acara who held his own and co existed. Anubias barteri on lava rocks was the plants I kept. They were the only plants since each plant was over a foot long lol! The fish loved the plants!
