I was hoping to mix some Peacocks,(around 12 or so) with a Jewel Fish, some Ruby Greens, a Archocentrus sp. "Cutteri", a couple of Blue Acara's, a few Firemouths, and a couple of Rainbow Cichlids. I'm not to sure that the Rainbow would work out with the others. I would keep the ph at 7.8 and have Hard water. The tank is 96" x 36" x 24" tall. The temp usually runs just under 80 degrees. What do you think of this combination??
