I have been vacationing over the past week, and just came home to a sick betta. I had a trusted person fish-sit for me, but apparently said fish-sitter apparently was having a little bit too much fun feeding my betta. I found the tank littered with rotting fish food, and my poor betta sitting lethargic on the sand. I immediately did a 50% water change, and got as much food out with a turkey baster as I possibly could, but there's so much of it. My betta doesn't look to be in good condition, I still have to test the water and completely assess the situation. Thankfully, if it is an ammonia, nitrite, or nitrate issue, prime has that taken care of for now, I'm gonna do another 50% WC tomorrow. Anyone know if I can do anything except clean, do water changes and hope he recovers?
