I just found myself the owner of a beautiful red male betta (I think he's a crowntail) that I've named Raphael. I currenty have him in a 2.5 gallon glass bowl, but I have a few questions about how exactly it should be set up.
I would like to get him a live plant, but considering the small size of his space, what kind of plant would be best?
Should he have a heater and if so, where might I find one small enough?
How often should I perform water changes since he currently doesn't have a filter? Should they be partial or whole water changes?
I would like to upgrade him to a five gallon tank with a filter, but that will have to wait until I have some more money.
Thanks in advance
