I just inherited what I'm guessing is a 1 gallon / 1 fish beta tank. I've got a male beta in there now and am looking for some pointers on water changes and some other things. Can I can give the guy a girlfriend if I frequently change the water. I feel bad for the guy who lives his entire life in a cubicle. Is it bad for me to change a portion of the water every day when I come in to work? Should I be worried about weekend neglect?
