Setting Up Livebearer Tank

I currently have a 10 gallon with 6 male guppies and a fully grown mystery snail. I want to upgrade to at least a 30 gallon. I love livebearers and was wondering how much of each I should put with my current stock in the new tank? I also want a school of cories with them as well. Any suggestions?

 

You could add about 3 times as many fish as you have now in a 30G. I'd say 12-18 guppies max and maybe 5 cories, it also depends on how many plants and/or decorations you will have in the 30. If you have a lot, I'd recommend throwing a few ghost and algae shrimp in the mix to help keep everything clean

 

If you add any females, you will have fry, keep that in mind. (Guppies that is)

 

Is it possible to make it all male? I really don't want to deal with babies. I don't have any plants as my huge snail will uproot it (he always moves/knocks over my tank decor). It's currently a SpongeBob tank and it's quite funny seeing him lift a rock to "go into Patrick's house" haha. I was thinking other fish like sword tails, mollies, etc. Just not sure how many of each. I will most likely be purchasing the 30 long.

 

Sure...as long as you know the difference when you buy them!
