Betta Fish: My first tank :)

You are welcome to rate it as well. It’s a six gallon corner style tank. I probably got my fish early but he is doing great. I also have a mystery snail which I find entertaining and a nerite snail who escaped once. He hangs out above the water. I don’t think he’s happy and I don’t know why. My fish is a crown tail (Mr. Fins) and he seems to be a happy and healthy fish.
