Greetings, I just got my normal 5.00 Betta yesterday, but I am taking every step to insure I give him proper care at all times. I have him in a filtered tank, thermometer to gauge water temps, water testing kit for weekly water testings, bought the premium brand pellet food, have the water treatment stuff, and am doing regular water changes. So to answer your question, yes. If I paid 25.00 for a fish I would def do all of this stuff to try to keep it alive, however I feel that even a 1.00 fish deserves the same type of quality of life that the expensive ones do. Cheers!!
