How Many Datnoids Could Live in a 75G

[Deep Blue Sea]

I was wondering how many Datnoids I could keep in a 75g for life?
and say I wanted to keep 5 in it how long could they last before I put them in something more around 170g

a few years...

Id say none for life and maybe 3 NTTs in the 170g as they dont get quite as big as ITs but have to think about tankmates if any and should be ok for a maximum of 2years in the 75 depending on growth obviously.
