|CrypticLifeStyle||Yeah I use pool filter sand in my tanks. Havnt experienced it myself. Wonder if the carbon theory's also apply to it too. Barbel hith|

Experiments have been done keeping corydoras on glass fragments substrate with out issue. I've seen substrate in Venezuelan Orinoco streams that will scrape your hands and feet raw. I've seen issues come up on planetcatfish where even with beautiful sand, guys corys are suffering fin and barbel erosion.
Fixing either one will likely reduce the issue.
Wild corys in Columbia, note the not so smooth substrate.

Also when serving their purpose they do, and can be dragged on substrate. If one were to think if they dragged a piece of their body across substrate you would experience scratching of the skin, possibly cuts etc etc, substrate digging, but most refuse to accept that for whatever reason.

you beat me to it Papwalker, I was going to say the same thing, Mysteries everywhere.
My question is do Angels suffer the same HITH as other Chiclidea? I don't run carbon on anything but I was curious. Purigen is all I use for chem filtering.

[/I]It would be interesting to see pathology comparisons between FW and SW cases.
It's a bit like the substrate and barbel erosion issue with Corydoras.[/COLOR]

Well my experience with carbon was the tanks i ran with carbon years ago the fish seemed to get hith, and the tanks i didnt never got it. A lot being the same species. All the tanks were on the same maintenance schedule, same water, all CA/SA species. I never use buffers.
At the time i had a really big batch of tapajos redhead juvies. Half the batch got hith, and split tail. I ran a lot of carbon on that tank. Uncle Ned from Uncle neds fish factory came over, and pointed it out, and explained there was a lot of discussion going on about carbon dust being the culprit. Since that day years ago i havnt ran carbon on any tank period. Never had a case of hith again.
I know a study proved carbon was the case in a saltwater fish study, but there's argument against that study for freshwater fish, cause they were salt water.
After that article i'm almost convinced its at least one highly suspicious culprit, but i do agree with some other arguments too. It's such a mystery still which i find odd.
I also read carbon removes vitamins, and trace irons, and other minerals from the tank water too which could be a combo factor as well :-??

You can find anecdotal evidence where the disease developed without carbon.
You can find anecdotal evidence where the disease developed without hexamita.
The only thing I could sniff out as the common mechanism might be loss of factors caused by their adsorption in carbon or obstruction by the parasite.
There is also a school of thought that believes it is a factor of the quality of the carbon (phosphate leaching), yet others point out that phosphate buffers are often used with no ill effects.
It may be that the use of carbon make the fish susceptible to hexamitiasis.
I guess until this directly affects aquaculture it will be unfunded and remain controversial.

|CrypticLifeStyle||That print is so out dated though, 1994. Back then they thought it was parasite related, now they arnt so sure. There's a little list of suspect causes. I've always been a fan of the carbon argument as i've seen this in real life, and the difference of using it and not using it, and most reputable shops wont use carbon.|

The combination of cooking our food, and having access to clean water, and having waste disposed of in a sanitary manner does wonders for cutting down on parasites and disease.
Even so, there are probably many more parasites in/on you then you realize. Most of them are relatively harmless and difficult to notice, like those mites that live in most people's eyelash follicles.
Just for fun, give these a google image search:
Anyways, yeah, having good water conditions does wonders, but also just having some control over the tank and food cuts out a lot of parasite vectors.
