Would you be able to post what kind of antibiotic @ what dosage was injected?
Also volume of med as per its weight. Knowing blue acara and judging from pic, it probably weigh around 125g (~1/4 lb) unless vet actually wieghted before determining the [conc]/volume which I always did for large fish )~ 16" Queen Trigger, etc, etc) in order to determine correct amt to be injected.
Such info can be life saving info to some fish keepers including myself.
And as well as name of antibiotic to be used in the water?
One injection is enough?
Dead common parasites such as??? Does that include bacteria/fungi as well as term parasite can be very broad in the vet's mind.
Wondering why he expected to find just high NO2, not NH3, especially in well established tank though??
Hope all goes well!
