I'm upgrading my 10gal tank to a 20gal long, and I'm considering swordtails. I wouldn't add a ton, most likely one male and three females. I have three platy, 2 cory cats, and one male betta named Dragon. I also plan on adding two more cory cats. Now that I'm typing this, it seems like it may be too many for that tank size, haha! Anyways, just to satisfy my curiosity, what is the minimum tank size for 4 swordtails?

20 gal would be good for not too much fish because you have to consider their size. I can sorta tell you more if you give me the sizes of your fish. With what I can guess from the lengths I've seen of similar fish, you'd need somewhere around a 32-35 gallon if you want all those fish. Hope this helps!
