Well the tems u have, u can expect a 2-4" growth a month my three are averaging around 3" a month right now then they slow down from what I've read and been told around the 2' mark till they hit maturity. So its a possibility you may only wind up with tems if the others don't keep up a half growth rate to the tems altho the orinos and monos are the more aggressive ones so they may have a chance. I had a 9" orino try to eat a 6" tem and it got its head in but it freaked out and spit it back out cuz it was way to big to eat it
