Question: how many ASFs can I keep in a grow out tub? My tub is around 4x2(maybe a bit smaller but it is def a good size, about 10in longer than a 66qt sterilitr tub)

I have two water bottles and always plenty of food. Right now I have around 50-60 in there, mostly just weaned, a few medium or close to it.

They don't seem over crowded and I haven't seen or heard any fighting and the tub has both males and females.
