Protective immunity against Cryptocaryon irritans

No, Tubifex are a different animal bred in entirely different places.

Thanks, I will research a bit more. Have you ever try tubifex? (yeah they are dirty nasty, but since they grow in freshwater, I was wonder)
I will start to try your "inmunity tesis" (feed them like they are breeding) it make sense to me (so I will try it). I feed weekly live artemia and copepods, but I wil focus also now on fresh food (not frozen) and some other foods like black worms.

Yes, I have used tubifex worms when I couldn't get blackworms. Blackworms are bigger and thicker. Cleaner also.

Would too many people explode if I said that your fish can gain immunity to pathogens by being infected with non-related non-pathogenic organisms?

And how many non-pathogenic microbes are in seawater? Apparently just the right amount!

By studying the density of microbes in different samples, Whitman
et al. (1998) estimated the total number of bacterial and archaeal cells in the marine environment (including the top 10 cm of sediment) to be somewhere in the range 10^28–10^29. The number of viruses in the oceans is estimated at about 10^30 (Suttle, 2005). This is an unimaginably huge number—it is instructive to write it in the form 1 million, million, million, million, million. If we include the subsurface sediments, this gure would be about 10 times higher. If all the marine virus particles were placed end to end, they would span about 10 million light years (100 times the distance across our own galaxy).

That's a lot of microbes and a lot of pathogens.....and the fish apparently need them!

Repeat after me: Immunity. Immunity. Immunity. Immunity.

Contrarian Sidenote: One of my more interesting customers at the LFS where I used to work, when he would buy a fish or coral, would ask for an extra large bag with lots of extra water from our system just so he could seed his tank more. Back then, even I looked at him funny and questioned him every time he did it....makes a lot more sense now!!

Hmm........
I wish I could research and collect data here in San Diego on fish mortality. Many folks here use saltwater from the ocean from the sand filters at the Scripps oceanic institute. It's free too.

Interesting, @saltyfilmfolks!

Seawater System
Two 1,200-gpm and one 850-gpm pumps supply fresh seawater to a gravity flume system that runs the length of the pier. Fresh and filtered seawater is available at various locations along the length of the pier. Raw seawater is available sporadically directly from the seawater flume. No instrumentation or sampling protocol shall impact performance of the seawater system.
