Hi there,
Out of a group of 4, I have 2 cory sterbais not doing well:
cory #1 - recently developed 2 white-ish bumps on both side of the body. Kind of ich but these look a bit swollen. However this guys seems to be great, swims with the other corys, up and down, nibbles all around etc. Seems happy.
cory #2 - no signs of infection on the outside (fins are ok, no ich, etc.). However fins seems to be clamped, stays in same place for a long while whilst the other corys swim happily up and down etc. Seems to have buggly eyes and breathing seems to be heavy compared to others.
Pictures of both corys attached
Let me know if you need videos, I can try and get something over to you...
Water parameters:
Q2 - I’m conscious corys needing to be in groups of 4+ so is it OK to separate the group having corys alone during the treatment?
Q3 - Should I also medicate the remaining fish in the tank to prevent disease spread?
Regarding PH - I have rocks, medium-heavy planted tank, wood etc. to help bring the PH down although not very successful. From measurements taken on tap water to the water in the tank there’s very little difference. I’m looking to keep stability as advised on YT videos as opposed to use chemicals and eventually crash the PH…
THANKS A LOT FOR YOUR HELP, TIPS, ADVISE.
