markings will start to show at around a foot you could prolly keep him in a 125 for maybe 9 months plus or minus depends on how good your water params are and how much you feed him and what you feed him

They may be able to last 1.5 years MAX. in your 135....depends on how much you feed em and how fast per month they grow. I would only let em get to 12" till you need a bigger tank! Probably only a year or so!
