My Betta has been fine until recently. He has a very hard time reaching the top to eat or the get oxygen. He is on the bottom and when he tries to swim up, he sinks :(. I have him in a Betta Bowl with a fake plant. There is no filter or heater, but I changed the water 10 days ago. I change it every few weeks and he has been fine, my previous betta lived 6 years. This betta is only a year old.
I plan on getting a 2.5 gallon filtered tank very soon for him.
Why can't he swim? How can I help him? Should I reduce the water to let him get to the top a little easier? Do you take him out of the bowl while removing water? Please help. I hate seeing my betta like this.
