I currently have a betta who's ever so picky, and wont eat anything I give him...He's been like this for about 6 days, and I've had to move him to a QT one gallon tank due to a major tank leek in his other one, as well as a heater malfunction during the night. The QT tank I have him in has the only spare heater my friend could give me, which is an awful cheep one. The good one I got comes the 20th or the 21st. Is it the lack of heat that has him not wanting to eat? Is there anything I can do for him? Feedback would be lovely..
