Cory julii - just keep dying

Post by jhd »

10 weeks ago I bought 3 cory julii to my community 29g tank
2 weeks later: one cory started scratching his body on the sand, fins clamped and most of the time motionless on the bottom. I separated that one in 10g qt and treated for parasites with malachite green. Completed treatment no change, fish still on the bottom, fins clamped. Treated with E M tablets (antybiotic) no change, a week later died.
Bought a female cory julii to have 3.
2 weeks later the new female fish stopped being active, stays at the bottom with fins clamped.
That has been going on for 3 to 4 weeks. Since the first one died, I do not treat this one, have no idea what is wrong.
Present: the female cory julii getting worse, looks like she is on the way out. One eye is cloudy,fish sits on the bottom with fins twitching from time to time. Fins clamped. Breathing heavy, but all other fish breathing is fine. Two original corys still active, but noticed that they started scratching gill area against the sand. If pattern is the same, they should be all dead in 3 to 4 weeks.
I have no predators in the tank
Neons, otos and pearl gouramis are fine in this tank. Only corys affected. Water: nitrite 0, ammonia 0, natrate 0, ph 7.5, kh 6 temp 80F. Water change 20% weekly.Planted tank.
I was told corys are imported from Czech Republic. I do not know if that could be a factor. They all are treated for parasites in the reputable store as they arrive. They arrive approx 8 to 10 weeks old
I do not know what is wrong.
I mentioned this problem in the chat room, sorry to repeat myself.
Can anybody help?

The signs look like gil flukes and the treatment you have been using will have little or no effect at all. They need to be treated specifically.

treating for flukes with Life Bearer, the only med I have for flukes
I heard that Clout is better but I do not have it and I do not think I have time to wait till I get it, things look bad. Active ingredients are dimethyl, hydroxy and trichloromethyl phosphonate.
Hope this will be enough to cure them.
Thanks for reply.

Well, although the weakest one did not make it, the rest of corys are not flashing any more and happily search for food all the time. I did take the weakest one to LFS and they looked at him, the opinion was gill parasite, gills were pink instead of red. They did not have microscope there to look closer.
Thanks for info.
I did buy 4 more and they are in QT for next 3 weeks. My LFS was the only one I could find selling cory juliis.
Thanks again for input guys.

I lost another 2 juliis from the additional 4 I bought a month ago.
I can not figure out why.
The only sign is they become lethargic and clamp fins. Than they roll the tail back towards the head and slowly roll on their sides. No other sighs on them visible, maybe these affected ones are a bit lighter in color.
I have currently 5 left and another one of them exhibits the described symptoms. I think I will terminate her in order not to spread whatever that is.

Are juliis difficult to keep, comparing to other corys? If more of them are going to die, I am giving up on them. :(
