id be worried about the rtc as they get bigger, itll try to gobble up anything that can fit in its mouth. The jardini I wouldnt think would be a problem, i've heard they snap when they hit 8 inches though and just freak out and turn into murderers....just what ive heard though
eventually your gonna need a bigger tank for the ornate, instead of the RTC you should get a smaller catfish and with the jardini i wouldnt take the risk
just moved my rtc into a bigger tank and now i just pick up a silver arowana and it is in the 90 with the jardini i havent bought the ornate bichir yet and i was wondering what they eat and what temp the should be so let me know and thanks everyone
