There is a guy near where I live that has a 10 gallon tank for $15 that's already cycled that comes with a filter. I was thinking of putting my guppies in there and I wanted to know what you guys think of buying the tank and adding some cherry shrimp and some guppies. I would add around 7 guppies and around 4 shrimp. What do you guys think? Or do I need two separate tanks?
