Symptoms and Treatment
How has your betta fish's appearance changed? The same night I added my Corys I noticed one small white spot on my Betta around his eye. I thought he was getting ick. I went to bed (all the stores were closed) and when I got up half of his head, and his eye, were completely white.
How has your betta fish's behavior changed? Very lethargic, wouldn't eat.
When did you start noticing the symptoms? Less than 24hours ago
Have you started treating your fish? If so, how? I got up this morning, bought some Maracyn, and aquarium salt.
Does your fish have any history of being ill? No. In fact, I was really excited because he was getting lots of color compared to when I bought him (he was all black).
How old is your fish (approximately)? Ive had him 2 months.
I am pretty upset that he died. I was quite attached to him. I really thought he just had ick and that I could handle it easily. He went from looking fine, and acting healthy, to being very lethargic and actually dying within 24hours. It looks like the white spots were eating away at his face. I am pretty upset because I am sure the fish I added are what caused the death. I just got worried that the small quarantine tank I was keeping them in was really stressing them out (Corys). Ironically I was buying the fish to help keep the tank in good shape for my Betta. What could this have been that killed him so quick? (I thought it was Columnaris) And what should I do to clear the tank of whatever this was? I bought a 10gallon quarantine tank for future illnesses and new fish, but its too late for that now. Please let me know so I can prevent this in the future!!!!
