His tank is only a gallon (I know, he needs a bigger one, but I can't go and get him a bigger one yet), he has a filter that came with the tank and so far has been working smoothly. No live plants, I have the Tetra BettaSafe water conditioner that I use. His last water change was last Monday, and I'm changing his water later tonight. I've had him for a little under 2 months and he's had the same tank since then, I've done one full tank change a little under a month ago. His tank has a heater and thermometer, and its stable at 79 degrees. I feed him once in the morning at once at night, but he's ok if I don't get the chance to once or twice. He suffered some fin rot and ammonia poisoning at the beginning but he's all healthy now.
Think he'll be okay without me around from this coming Thursday (Nov. 3) until Nov. 13, when I get back?
