I got my king Betta, James, in the beginning of March at the Petco down the street. He was a bit timid the first first days after I brought him home (but I expected that). But in no time he was swimming around having a good ol' time flaring at his reflection and at my finger. It was about 2 days ago that I noticed that he had become sluggish and he had not touched his food. Concerned, I looked at him to see if I could identify any physical changes.
Come to find out, he is constantly flaring. Here are some pictures:
My Water is healthy for him, I did a 100% water change about 5 days ago.
2.5 gallon tank
no air stones
If anyone has any suggestions or questions please ask. I know there isn't much information out about the king Betta.
