Well I haven't got a Betta yet but I have been looking really hard and have been thinking about getting a gold fish starter tank with ari filter and water filter. It will be about 2 gallons or bigger. I talked to a guy at this exotic fish and pet shop and he said they can put a order for a crowntail for me. I looked a Petsmart but all of the crowntail bettas are red and blue colors not I kinda like the green mixes. I work as a Server so I have to wait after Sunday to purchase the tank I want and then have the guy put in my order for a crowntail. I think their bettas are cheaper than petsmart but if they aren't I still know I'm probably getting a better fish since they seem to keep them in large tanks with more othe co-existing fishes and look much happier.
