3 days ago I noticed my largest 12yr old male was swimming by himself and not coming for food. I pulled him yesterday and noticed his eyes and face were a little swollen, he has no signs of any scrapes, cuts, ulcer, body and skin/scales look great. Hes not sitting on bottom, no clammed fins and no flashing. No other fish in pond show any symptoms, they are active and still eating a little every couple days.
Water temp 59, ph 8.3, kh 8-9 drops, nitrate 5, ammonia/nitrite 0. Filter cleaning and water changes every 4-5 days.
I'm assuming he picked up something bacterial. The only other thing I can guess is hitting his head on pond walls or DIY retro BD, he looks exactly like a female did after spawning a couple years ago and getting banged up (the swelling went away within a week on her).
I have on hand
BGDX, I know its for gill disease but does it work for other bacterial infections? This has been in my medicine
chest for a couple years (unopened bottle), how long does it last.
Tricide Neo, It would have to be put on as a spray (1gal pkg) would I just spray his head or whole body?
Amikacin (human strength) but no sterile saline, I'm sure I can get some.
Should I treat with one of these options or should it be a wait and see seems how I dont know if its bacterial or injury. I dont want to wait to long as we have some very cold weather coming our way (pond is covered), but pulling and treating when its only 40ish air temps will be much more stressful for ME then the koi.
