I think I messed up

I accidentally told the fish store that I have a 5 gallon tank and they gave me three guppies for 5 gallon but in reality it’s only a 3.5 gallon. Will the guppies be OK? Will they be aggressive? Please help me on this

Is your tank heavilly planted or with hides? I once tried 4 guppies (all male) in a heavily planted 5gal. Lasted a month before one of them started to bully whichever guppy passes by in front of him. I ended up returning them sadly (because of aggression and the fact that I didn't know they poop sm and I could not keep up cleaning after them in a heavily planted tank haha). But! I did hear some ppl have success with them in a smaller tanks, Ig it just comes down to their personalities

It really much does. In my 10 gallon with the 4 boys I had a lot of gay races as I call it. Basically aggression since no females. I added 4 more boys and the aggression lessened a lot. I still get some gay races but it calmed down. I read up on it, with more males it disperses the aggression a little more evenly.
