i have a beautiful ID shark and it is about 14inches long, just posting this to see what the average size id sharks you guy may own and how big do you expect them to get. let me know your biggest sharks..(cats of coarse) in your tank
U have a Rtc, rtcxtsn, and a channel don't u? Think I remember reading that in one of ur post. If so I would wait until u have room in a grow out. They grow at a medium speed but than slow down. Really I think they would need a 6month head start on those cats to stand a chance. I have many of the same cats btw.
