Hey everyone I need your help. I own an Orchid betta and got him in August. His name is Pluto. He is a black sort of metallic color and is normally very feisty and a good eater. He is in a one gallon tank with a filter.
Over the weekend I went away so I left him with a friend. She said he was very lethargic and at one point thought he died because he wouldn't move. I did a partial water change and he seems a bit better for a day,but got worse again.
He is laying on his side and his back is bent in a S-shape at the bottom of the tank. He used to have a straight back. He rushes to the surface occasionally for air and darts back down to lay on the bottom on his side. He is black in color and looks about the same color wise (He has lost weight). He isn't eating well. I just noticed one little white spot on his mouth so I did a full water change and removed the decor in case it was infected with something.I left a few stones and a leaf hammock in there. I added anti-fungal and antibacterial (API brand) to the water. I removed the filter but left the water running because he appears to be gasping.
I don't know what is wrong. Some of the symptoms sound like TB and then the white spot makes me think he could have a fungal/bacterial infection, but overall I don't know!!! Help please!!
