I need help. It's been months since I've been on here and it's because I've been busy. I found out my tank was overstocked at the end of the school year. That was a bad time to find out because I had finals to study for. I spent lots of my time trying to figure out a way to make it work (I have very little space to simply just, get a bigger tank). I was stressing about fish and tests... great! I thought I had found a solution and was gonna start as soon as I got back from my summer trip. And then dropsy came back along with summer. I came back from my trip to find two fish with dropsy. One danio with dropsy acts totally fine. He eats, swims, plays, etc. The other danio was upside down (but alive) this morning. Now he's right side up (on the bottom of the tank though) but on further inspection I think its TB. I don't know what to do. I have clove oil but I'm beyond just worrying about the two fish now. What about my other fish in the tank?? Will they all get TB?? I just need someone with experience to tell me what to do. I'm gonna explode. I never know what to do and I can't believe I'm this bad at keeping fish healthy.
