I’ve had him for a year. I’ve had the tank since I got him but I’ve moved twice and he’s come with me so his tank was newly set up again about a month ago. I just noticed the bubbles today and I don’t think he has had them more than a few days (if that). His tank is on my desk so I watch him...
My betta has two lumps/bubbles that are growing on his fin. This is the first time I have noticed them but they seem to be pretty large (the one picture is the small one). Does anyone have any idea what this is or what it could be? (He is acting normal and eating normally)
