thanks for responses. No that is not the only reason I would get a tank, just a bonus. Have had fish before but as we are seniors I thought I would go for a smaller set up and make it easier on myself. brit QUOTE=rmiller;2683131]Small tanks can be more difficult to maintain, especially for a beginner. With just a betta, you'll do just fine, but if you can get a 5-10 gallon tank you'll have less struggle to maintain healthy water for your fish.
As for the humidity, water will evaporate regardless of the fact that you'll have a lid on the tank. Depending on the size of the tank you may or may not notice a difference in the air. If that is your only reason to have a tank, please get a humidifier instead.[/QUOTE]
