Not sure what happened.
It was cycling.
So, it was a 10-gallon cycling tank.
I tried to ask another forum for advice, but they take days to answer.
In their emergency forum... I know, right?
I dont know what to do.
I have an old 5-gallon tank that I can use for him (it's too small in my opinion).
The filter hasnt been running for a few hours.
Thats because I dont know how to set up the unused tank.
I just wash it out, fill it with treated water and some gravel, and put everything in?
My betta's in a 6x3 inch potato salad bin, and he's content for now, but he cant stay there forever!
