I think they will uproot things, they get 12" but it takes time and good feeding.
4-6" in 2-3 years is what you'd be looking at as a lower end assuming good care. ADA AS is not good for these fish IMO.

I'd go with Botia striata,B. sidmunkthi instead.
Stay small, can be seen during the day, schooling, not that aggressive.
