Well, the first time it happened I ran to a pet store and searched for fish medicine, and though the cost of the medicine was about 10 times the worth of the fish, I decided to do it anyways. How can I flush a fish that has a good chance of healing with good conscience?
[My small fish tank with boyfriend's fish and the other fishy. It's green because of the antifungal medication.]Eventually fishy healed and my tank rode a healthy equilibrium for a few months.
Now I've put more medicine in the tank and I'm sure fishy will heal again, but I mention this story just because its always a little adventure for me to try and save animals. I hope in the future I will make a career out of that, so for now, I do what I can.
This isn't the only time I've helped my animals, there was another gold fish I bought a long time ago, and a week after bringing it home I found a weird growth/parasite on its side! (needless to say I won't get fish from that place again!) I was pretty creeped out, but after doing my research I discovered it was an anchor worm. I read up on how to take care of that too, and after removing it, that fishy healed just fine.
Perhaps fish medicine is boring to all of you, so I'll mention what I've seen working as a bather and how I got to see some horrific cases of sick dogs. There have been ticks(rare where I live), horrific ear infections, open sores, dogs with nails that had grown so long that the dogs bones had broken from walking on them, dogs covered in warts(mostly hard to look at), sores on puppies from shock collars, a dog with a UTI that pissed on herself constantly, really bad allergies and dogs with teeth rotted to the gums whose breath could knock out a parade. Many of the owners knew about their dogs health issues and were treating them, but sometimes we had to give them stern advisement to take them in to see a veterinarian. There was nothing I could do working as a mere bather in a grooming salon to help these dogs, other than to give the dogs a good bath and answer their owners questions. But I did try to make the dogs as comfortable as possible.
I know I'm very silly, since I'm just a college kid studying biology, but I do find joy from these simple little gestures towards animals.
