So, just registered here. I figured I'd go on and say thank you to you all. I never realized until I was contemplating on getting a betta and coming across this site the space that they really required and the heating and filtering needs. After researching and reading a good percentage of the threads here, you all convinced me I need a betta, so I set out and got a ten gallon tank with a filter and heater. My crowntail, Hermey, and two apple snails to go in with him. I've never seen such a personable and happy fish, anytime I try to take a picture of a snail or any part of the tank...here comes Hermey casually drifting into the picture to make sure he gets in the shot.
This is a great site, thanks for all the info.
