So, as I explained in another thread, my betta was in a 10 gallon, with about 4 gallons of water.
The tank broke so I bought a 1 gallon tank and put him in it. He was fine yesterday but today I noticed his gills going in and out like he is heavily breathing. He comes up for food and swims around, but is laying on the glass gems at the bottom, and looks like he is gasping for air and its making me really nervous.
He still eats. His water was changed yesterday when he was put into the new tank, he was acclimated. The water was the same source and method from the water I used in his last tank and for changes. His appearance is the same, and nothing else has changed.
I know that it may take a bit of time to get used to the new home, but I don't think the breathing heavy or whatever it is, is normal. It has got me worried.
