I am wondering what is going on with my fish.
I got my first betta fish two weeks ago. I kept him in a 1 gallon plastic bowl and cleaned it every three days. The water was always clear, even whenever it came to the 3 day mark. I always cleaned it after 3 days, but the bowl really didn't need cleaned. He unfortunately passed away. He was not very healthy whenever I bought him.
So 2 days ago I got a second betta fish, and he is a completely different story. After a few hours the water starts to look cloudly. The only difference between him and my first betta is that he is in a glass 1 gallon bowl, and he has a heater. The water stays at about 78 degrees.
I'm new to owning fish , so I could use some help. Why does the water get dirty so quickly? It didn't with my first fish! What could be causing this? My new fish seems to be very happy and healthy.
I can't afford a filter at the moment, nor would one fit in his bowl since I have the heater in there. I know that betta fish do much better in a larger tank, but I'm doing the best that I can. Any clue as to why the bowl gets dirty so quickly?
