i don't think so. if it's 4~5 years old, then it's much bigger than 20cm. around 25cm or over, i guess.ok, thanks..but i thought it would take more like 4-5 years, but that is wrong then:?
I second this. Some are faster growers though.My experiences, one year from born - about 10-12cm, year and a half 16cm... let's see what'll be next year:d
