I just checked on my betta and he is extremely stressed out! Usually he greets me when I go in front of his tank but right now I noticed he was only swimming at the surface and he could barely go up for air...When I started watching him for about 15 mins I noticed he started swimming very sluggishly and was crashing into his plants and almost sinking into the gravel...he is dark navy blue in color normally... but right now the top and bottom of his face is all white.
He lives in a filtered heated 3 gallon tank that he really loves. I do a complete water change every 3-4 days. I prep his new water with conditioner at least for 48 hours before I do the 100% change. He eats his food. I am so upset I am trying not to cry. I have never seen him like this.
