Another reason that guppies and other schooling/social fish need to be in groups of at least 4-5 is that there is a social hierarchy (ranking) among the groups of fish. When there are too few fish or no fish at all the fish can get stressed or depressed without the whole group dynamic that they need and thrive with. A guppy may survive by itself, but you want your pet to thrive and be happy, not just live life on the bare minimums.

Sweeda im sorry, but i have to disagree. 20 gallons? For that many fish? The tank will be way to empty. Though I do agree that guppies do need to be in a group. I would say at least 4-5. (like Sweeda said).

I'm saying you'd need at least 20 gallons for you to be able to have PROPER SCHOOLS. Even then, I think it would be overstocked.

+1, guppies may seem small, but they are very energetic and use up a lot of swimming room. Trust me, once I got my guppies into my 20 gallon it seemed small with all the swimming around they did!

Agreed with Sweeda. Yes, a 20 gallon would be huge for the amount of fish OP has now, but we always say bigger is better!
Plus, she doesn't have them in proper schooling sizes. If the fish were all in the proper schooling sizes then OP would need a 40 gal min tank.
Guppies at least 5 - 2.5 inches each= 12.5 gallons
Glofish at least 5 - 2 inches each=10 gallons
Betta 1 - 2.5 inches= 2.5 gallons
glass catfish - at least 5 - 4 inches - 20 gallons
total= 45 gallons. approx

Fish that are very active need plenty of room to move around. Schooling fish are not going to be happy in groups of less than 4 or 5.
