HI, I have a 55 gal, with an african setup. I had my livingstoni and my male ob zebra die within the last two days. MY zebra was the most aggresive in the tank. I noticed that he was chilled out and not eating. Well yesterday, i noticed that his eyes were bulging out and he looked swollen. I rescued him to late. he died while in quarantine. It wasnt until 10 last nite that i noticed. I couldnt get the bloat medicine that I needed cuz the stores were closed. None of my other fish are showing signs of illness. Should i still treat the main tank, and if so how? Please help, i love my fishies. My zebra just became a daddy too.
