Well, ±10%. I saw a school og fish with 103 fish in it once, but ij my fishtank i coukd never get above 90 before my tetras would just all immediatepy rip each other to pieces in a terrible blood frenzy that turned the water pink.
It’s okay, i figured out a solution; if i just occasionally plucked one out and tortured it in front of the others or smashed it against the rocks with a hammer, i could get as many as three thousand to school together!
Eventually cracked the tank doing that though. Oopsie. Costs of docial cohesion i guess.
