Is it me or is Ich misdiagnosed constantly?

[2wheelsonly]

Been reading alot about different parasites and noticed people will post stories of tank coming down with ich and a few days later everything is dead.

From what I gather, ich doesn't kill that fast? Could it have been velvet instead? Velvet kills fast correct?

The more I research the more I read so many conflicting reports...

Having "worked" in this forum for about ten years, I see misdiagnosis frequently. Tank wipe outs almost never are ich. However that is the parasite most are familiar with, however. Visual symptoms are not definitive, behavior is nearly always the first sign of trouble.

What Steve said.
Unless you bring in a fish that is white with Cryptocaryon nodules, it should take a couple of weeks for Cryptocaryon to build up the numbers to actually kill the fish in a tank. Usually, if it's Cryptocaryon, you see it coming miles away as the fish deteriorate gradually.

If fish die quickly without showing much symptoms (or at least unnoticed by the untrained eye) it's usually something more vicious - Amyloodinium being the most likely suspect.

Also, with Cryptocaryon you will always have a few fish that are immune from previous encounters, or generally resistant (I've never seen Banggais with ich even if anybody else in the tank was looking like battered and ready to be fried). I also had it more than once that fish beat Cryptocaryon on their own without any treatment.
With Amyloodinium immunity, while possible, is much rarer in a aquarium environment. Usually, if you had a tank wipe-out out of the blue, you were dealing with Amyloodinium.

In addition to velvet killing quickly, most fluke infections are always misdiagnosed which also will kill quickly

Yup. It is so true.

YOU MUST QUARANTINE.

Must

Quarantine.

Write that down 50,000 times.

I think flukes is the real killer in this hobby. By the time you really notice them, you are in big big trouble.

Most successful long term folks treat with Prazipro always from the beginning.

In terms pf frequency I have observed here:

-cryptocaryon irritans
-flukes
-velvet
-brook
-uronema

I don't think flukes are actually that quick to kill fish as their reproduction is not as quick as with some protozoan parasites that duplicate by direct division like Brooklynella for example.
The issue is more that they they can go unrecognized for quite a while.
