I just did a 100% water change a day ago.. I used tap with four drops of Tetra Aquasafe Plus.. The tank is a one gallon with one plastic plant and glass rocks.. His fins look funny and I'm worried. They were fine before the change.. Please help me!
Boy that looks like my Ruby, but her's is caused by her sorority sisters. I'm not sure what this is. I don't think it's the plant, they usually cause clean tears, and it's not quite like what I expect with fin biting. I'd suggest you ask either Sakura or OFL (oldfishlady). OFL is our resident expert on ALL things betta, and if anyone can help it's her. However she's usually on in the morning. This time of night you might find Sakura on. She is friendly and knows quite a bit.
