I made the mistake of doing a 100% water change since my tank was cycled and i thought it would be okay. My betta was completely lifeless laying on a plant when I came home when he normally swims to the front of the tank and all over when I get home. I assumed it was from the water change mistake so I did a 50% change to help with ammonia. It has not helped his activity level and I m not sure if that’s normal. If he goes by his plant he’ll lay there for about 10 minutes and move somewhere else, just to sit there for another 10 minutes. I also noticed he has like a black outline along all of his fins. For the life of me I can’t remember if he’s always been like that or not. He does have a darker body and I don’t notice any holes or tears in his fins so I’ll post pics to see what y’all think. Does his inactivity after a 50% water change sound normal also? He’s eaten his normal twice a day meal but he’s never been this inactive.
