Fish antibiotics. Much cheaper, same stuff.
I suspect fish antibiotics are even harder to calculate dosage than my supply of ivermectin for horses. LOL Thanks Laz!
Fish antibiotic availability from my local feed store.
Amoxicillin-Clavulanate (Amoxicillin - I can get)
Azithromycin (I can get)
Ciprofloxacin (seems familiar)
Doxycycline (I can get and have some here)
Metronidazole (never seen it)
Metronidazole is used to treat infections of Giardia in dogs, cats, and other companion animals, although it does not reliably clear infection with this organism and is being supplanted by fenbendazole for this purpose in dogs and cats.[64] It is also used for the management of chronic inflammatory bowel disease in cats and dogs.[65] Another common usage is the treatment of systemic and/or gastrointestinal clostridial infections in horses. Metronidazole is used in the aquarium hobby to treat ornamental fish and as a broad-spectrum treatment for bacterial and protozoan infections in reptiles and amphibians. In general, the veterinary community may use metronidazole for any potentially susceptible anaerobic infection. The U.S. Food and Drug Administration (FDA) suggests it only be used when necessary because it has been shown to be carcinogenic in mice and rats, as well as to prevent antimicrobial resistance.[66][67]
Used in fish tanks so I should be able to get it. I do have some fenbendazole here. Just gave some to the dogs yesterday as a dewormer.
Some people claim fenbendazole cured their cancer.
Do you clean out the entire stock of guppy penicillin for one dose?
Same as the fish antibiotics you get from the pet store for probably $50.
