Had him for 7 months now. In a 3 gallon tank, no filter. Water is always cool. He gets natural and artificial light 10-16 hours a day. I Replace the water at my own discretion, usually every couple of weeks(it always appears clean). It has no plants inside, only rocks. I feed him HBH betta bites. 2 in the morning, 2 in the evening. It's what works for him and I. Sometimes i forget/am late. Latest i've fed him was 2am(probably shouldn't have). He's always hyper and still is. If i feed him now, he'll devour it so his appetite is fine.
Noticed he was swollen at the front. I changed his water 5 days before noticing this. Fasted him for 2 days. Read about peas, gave him one in pieces(took awhile to get him to eat it). 5 days later, no progress. Fed him another pea(this time he loved it). It's been 2 days. No progress. Suggestions? Patience?
