Hey Everyone! About 2-3 months ago, I bought 7 new false jullii cory cats. I took them home and started them in QT. Something quickly overtook them, and I treated with Kanaplex by Seachem to kill it off. I lost 3 fish, and had to go through 2 treatments with the meds. The anti-bacterial medications seemed to be working, but a few people here mentioned that it might be parasites. The other fish were never totally asymptomatic, so I kept them in QT until 3 weeks ago, when I deemed them OK to go into my main tank. I went on a backpacking trip for the last two weeks (got home today, finished with 9 miles this morning!!) and had my mom petsit while I was away. She fed every few days, and said they all looked great. When I got home, the symptoms were back. One fish was laying on its side near the back of the tank. When the fish first had the disease, they were on their sides, breathing heavily. When they tried to right themselves, they'd swim all over the tank sideways until they landed upright. They also showed some swim bladder problems, listing one way or another. Now, the one fish is showing similar symptoms, but not exactly the same. He flipped on his side, but his breathing wasn't nearly as heavy as it was in the fish that died. It was almost normal. He was able to right himself pretty easily, and isn't showing swim bladder problems other than the fact he was on his side for a minute or two. Now, my question: I am planning on treating the tank again with Kanamycin, because this helped them a ton the last time. However, last time it didn't go away, but there was a gap between the 2 treatments and the disease was on pretty badly. Does anyone have any advice on how to get the sickness to kick the bucket for the last time? Water parameters: Ammonia: 0 Nitrite: 0 Nitrate: 5 (planted with purigen) pH: 8.0 Thanks for all your help!
