Hey everyone, You guys know I recently acquired a female betta in my 10g tank. Well, about 5 days later she developed fungus on her eye and her fins, and about 5 hours later she died :'( I really don't understand, the parameters in my tank were more than perfect! No ammonia, nitrites or nitrates, and a pH of 7.4. Temperature was about 25 °C. The other guppies are perfectly healthy and barely ever interacted with her as she was always hiding or swimming lower than them. DDK pets think that she might have been sick before I bought her, that it was just invisible at the time. I'm really sad and kind of scared to buy other fish at the moment. Thought I'd share the sad news with you, only you can understand how upsetting fish loss can be!
