Mmiller2001 Posted September 17, 2020 Share Posted September 17, 2020 Quick breakdown. These guys just came out of QT, bit longer than 3 weeks. Week 1: Med trio Week 2: Gills red and flashing, dosed Paracleanse per box direction. Week 3: Ich X for 5 days straight. Plus a few days, saw no flashing and added to main display. Do Cory's just do this or I did I not get all of what was happening back in QT? It will be impossible to remove them without stressing the whole tank (75G, 7.4pH, 0 ammonia, 0 nitrite, 0 nitrate, 5 GH, 4KH) Thanks for looking.

Fadewood Posted September 18, 2020 Share Posted September 18, 2020 Dang, 7.4PH with all those tannins and wood in there? That's crazy. However I'm in the same boat, my water is almost 8 out of the tap. Takes a lot to get my water down to a lower PH. I've had cory's flash like this before, usually a water change fixes the problem, sometimes they just do it because they like the sand. I'm not sure. If it becomes excessive flashing, then you could do some salt in the tank and see if that helps ease things. Link to comment Share on other sites More sharing options...
Administrators Cory Posted September 18, 2020 Administrators Share Posted September 18, 2020 I would say something is off a bit. If they are continually doing this, I would try a 1 week treatment of Prazi. If there are no plants you could also add a tablespoon of salt per 5 gallons as a very mild anti parasite. I suspect that possibly there are some gill flukes, but its very hard to diagnose over the internet. Link to comment Share on other sites More sharing options...
Mmiller2001 Posted September 18, 2020 Author Share Posted September 18, 2020 (edited) Thank you both. My initial guess was flukes. I just ordered prazi but in the meantime I could dose Paracleanse. Should I wait for the Prazi or try the Paracleanse again now? I do have plants. Edited September 18, 2020 by Mmiller2001 Link to comment Share on other sites More sharing options...

At one point my KH dropped to 1 unexpectedly, and that dropped my pH to 6.8, which scared me. So now I keep my KH at 4 which holds that 7.4 7.3 well. 1 Link to comment Share on other sites More sharing options...

Being that you did 1 round of Paracleanse, I'd probably just wait. Even though Paracleanse has Prazi in it, I believe Prazi is a higher concentration being the solo drug.

AndEEss Posted November 2, 2021 Share Posted November 2, 2021 What was the resolution to this? I have a good number of cory cats that occasionally flash like this. But there are not other apparent problems; everyone appears to be quite healthy. Big appetites, very active, etc. Link to comment Share on other sites More sharing options...
