Well, like I said that depends on everything else. Take the 2 - 3yrs as a generic guideline, the reason I say that time period is most rhoms are around 10" by then. It would be wise to give it a new tank asap as not to impede it's growth.
There is no way a rhom is gonna be 10" in 2-3 years. they get about 5-6" the first year and then its about an inch a year after that. so your looking at min 5-6 years but more likely 7-9 because growth slows down even more after 7-8"
