Okay. I've been experimenting with all sorts of different fish trying to find a peaceful combination. I finally have a batch not fighting. 3 angels. 1 ornate bichir. 1 elephant nose. 1 severum. 1 yellow jacket and 1 silver arowana. They all are young and getting along. I have a 120 but know I'll need a bigger tank. If I don't ad any more fish what size tank would you recommend. They have a 240 for sale for 1000 bucks that I'd like to get but its only 6 feet long. I was hoping for an 8 footer.
