This isn't a Human or fish question, the fact is that antibiotics when used improperly contribute to "stronger" more resistant bacteria, which in turn represents a real health risk.
I couldn't agree more.
A for people meds are people meds and fish meds are different. Not true. Many fish meds are exactly the same (although not regulated to the same quality control standards as human meds) tetracycline for one, Maracyn is Erythromycin, also used for people (often prescribed to treat chlamydia- a STD. Now why would anyone prefer to get their STD cure from the fish store and blame it on their sick goldfish than have to take the prescription to the pharmacist? or perhaps have their mom receive the EOB in the mail for getting that prescription filled on your family health plan. Explain that one. It is also used to treat strep infections and anthrax among other things).
The label also says it will not interfere with your biofilter which is
blatantly false. It does not kill bacteria, it simply stops it from multiplying, so the infection dies its own death- it will also stop your biofilter from replenishing itself and growing- read on to see why this is so bad.
They should be pulled- primarily because the makers of these medications are practically criminal in their labeling. For example, from Maracyn two's recommendations for diagnosis and treatment:
"Symptoms of clamped fins, general listlessness, not eating or other unusual behavior can be caused by internal infections and treatment with Maracyn-Two would be indicated."
Maracyn says "Symptoms of clamped fins... heavy or rapid breathing........ change in swimming behavior or corner hiding can be signs of possible bacterial infection. All suspected bacterial infections should be treated immediately."
You have those symptoms? Test your ammonia and 99% of the time you have your culprit- advising fish keepers to add an antibiotic which will stop the bacteria in your biofilter from growing to address that probable ammonia issue- its abhorrent to me.
They claim that Maracyn II treats dropsy - dropsy is fatal. It happens when a fish's organs begin shutting down and they can no longer excrete the excess water that accumulates in their bodies through osmotic pressure - this pressure is constant on freshwater fish, throughout their entire lives, every moment of every day, but is usually expelled as urine. Dropsy is when a fish can no longer do this. It is most often end stage renal disease. Kidney's kaput. You show me someone who's cured a fish of dropsy and I'll show you a liar. I'm sorry. I'm sorry to be so blunt, but it is true- and isn't education what this conversation is about? Dropsy is a symptom of dying. Yes, kidney failure can be caused by bacterial infection- but it can be caused by a multitude of factors- even if you could be sure its bacterial, which is no more likely than any other cause- once the kidneys shut down to the point of the fish swelling to twice its normal size and looks like a pinecone, you're not brining them back. That's why your doctor puts you on the transplant list when your kidney's fail instead of sending you to the pharmacy with a prescription for penicillin. Dropsy should be treated with clove oil, the sooner the better. (clove oil is a nice way to euthanize a fish)
Until the medication makers become responsible AND TRUTHFUL in their advertising, their products should not be made available. If the makers won't give you ethical professional advice on the proper use of their medications, then it is very responsible of petco to require we DO get professional medical advice from another source before dispensing such meds to the public.
