I do not have one but am planning on setting one up as a hospital tank. At the time I hape inexpensive and simple fish that haven't been sick and are easily replaced. I know it sound mean but I would try to help the fishI f I could. The quaantine tank just isn't in the budget...yet. what is a good size for a qarantine tank and is it totally necessary.
I had a quarantine tank, but I couldn't figure out how to keep it cycled in between adding fish. It was good cause I used it to clear up the ich on my neon tetras, but a couple weeks later when I put an angel in there it died. I know that there is a way to do it, but it just wasn't working for me. Now my tanks are pretty much stocked, but next time I set up a tank I plan on getting another one.
I don't generally find it necessary for me. I kept fish for a long time, years ago... and the one and only time I used a hospital tank was when my dad bought an oscar that was already sick... he was so bad off that I honestly didn't think he'd make it, but he pulled through and became the meanest one he had.
I am now using my other 29 gallon as a QT... wanted to shut it down, but thought, may as well use it if I need it for sick fish... Not going to add any fish in there so will have to keep an eye on the water perimeters to keep it cycled.
