How many threadfin acaras?

[Crunchycrouton]

I have an empty 75 gallon that is cycling right now, and I’m trying to figure out what I want to stock it with. I’ve seen mixed responses when it comes to acara tank sizes, and I’ve heard you need at least 3 since they are social. So how many gallons minimum would it be for 3? Or if 75 isn’t enough I will just stick to angelfish.

They are social but can be very aggressive with each other in small numbers so I would suggest at least 6, which would mean a much bigger tank.
3 is never enough for fish that live in groups.

Okay thank you. I figured it was at least 5 but I’ve heard other things too, so I wanted to come onto here and get other opinions. I’ll just stick to my angelfish plan then
