Hi everyone, lately my male betta has been very lethargic and I almost always catch him laying on his side on the bottom of the tank instead of his favorite plant...I've had him for almost 4 months and he has been battling fin rot, his fins have been healing very nicely, until about a week ago. I do have a decent sized diatom problem that has erupted, could that contribute to the fin rot or causing him to lay at the bottom? I thought diatoms are harmless to fish. He also has a "tumor-like" bulge on one side that had been there since I got him, I didn't notice it at the time of purchase and it doesn't seem to affect him. He is in a 15 gallon tank by himself and I do 25% pwcs every week. Amm is 0, nitrite is 0 and nitrate is 20. Temp is kept at 79 degrees
Does anyone have any ideas what he could be suffering from? This started about a week ago and in seeing him lay at the bottom more and more sometimes not moving until I practically dance in front of the glass to get his attention and I'm worried
