And I've really come to realize how cute they are.
Yeah you'll want to bump your water changes up I don't know exactly how much though. :/
I recommend finding a nice 5 or 10 gallon for the three guppies (5 for just the 3 10 if you wanna go ahead and add more) but if you're tight on cash I understand. I'd try to take the corries back for def and if it doesn't work out I'd go ahead and leave things until you can find a way to separate the guppies and get another cory. That's just me though. There might be a better solution to your situation that I'm not thinking of.
For future stocking advice I'd head over to the Compatibility sub-forum. They give really good advice there. =]
