Hi everyone, I'm pretty new here. I used to have a betta a few years ago. I am only 13 now. And so I am starting to get back into fish now, I have a 10 gallon with a female guppy and 4 fry. And then I have an empty 2.5 gallon, which I was thinking of putting one male betta in. I have researched bettas a LOT!!! But I've heard they are usually very active unless the water is too cold, they don't have enough room, or they are sick. Is this true? Because the other betta I had didn't move hardly at all, and it could have been because he lived in a bowl or because I didn't have a heater for him, but he lived for about 2 years. So my question is basically Are Bettas Very Active?....thanks so much for any answers.
