Yesterday I noticed my female betta acting strangely. She was sat on her leaf gasping for air. I put a little food in her tank to see if it would interest her, it didn't.
I did a 50% water change (my tank is fully cycled)
Later that day she was facing diagonally down at the bottom and couldn't get to the top.
I took a water sample to my LFS and they said everything water wise is fine.
That evening I put her back on to her leaf so she could get breathe from the top of the tank.
This morning I found her at the bottom of the tank completely discoloured.
I have put her in a smaller container and floated it in her tank so she can get the the top to breathe a little easier.
Is there anything else I can do??
