What fish should I keep?
I'm setting up a 10 gallon tank, and I want to figure out what fish I want to put in it so I can meet their needs w/ plants and such. Right now, I have my brother's loach (no idea what kind, it's thin and around 2 inches long) from an aquarium he stopped caring about, and I'm thinking about getting a dwarf gourami and a few guppies. The issue is: how do I get a few guppies without ending up with a swarm? And how many should I keep? A trio of females might come with babies, but I've heard that male guppies can get aggressive with each other. Any recommendations?
