I have a betta fish, and I enjoy taking care of them. I just got this one last week. When it came, it was very healthy. I put in a 5 gallon aquarium with a zebra fish and a male guppy, no decoration because there is Methelene Blue in the water. They'll be transferred to the original tank that has decorations today when i clean it. Often, the betta fish just floats at the top in a corner and satys there, fins closed and lame. What's the reason for this? Temperature? I doubt very much that it is sick. the other fish swim fine.
I don't think its toxins in the water because the water is new, and with methelene Blue.
The betta gets aggressive in a semi normal manner with mirrors, meaning that it doesn't flar up immidiately when an image is seen, but a while after.
How can I get the fish to be normal, and swim around etc, instead of just looking, well, like a plant?
is this how betta fish are?
Also, when cleaning the tank, how much water to change?
