I've got 3 clown loaches, and feel salt is a must. I keep my clowns in a ratio of 1 tablespoon of salt per 5 gallons of water and they do absolutely fine, I'm sure if you add some salt to your aquarium your clown loaches may well recoveer. I found most people who dont use salt often suffer from bouts of ick and fungus etc and by simply adding salt this will help reduce/eradicate any such problems, certainly ick hates salt so by adding this you should find you greatly improve the situation . My only advice is to add the salt slowly take a few days to get up to the salt ratio I mentioned above, dont just throw the whole lot in instantly. By the way enusre the salt you add is aquarium salt and not just your bog standard table salt, table salts etc contain chemiicals which are known to be harmful to fish.
Also I'm going to suggest something that no doubt every one will object to but clorine isn't a massive threat either in low doses infact I find it can help. For example I do a 20% water change of my aquarium once a week and dont bother with decloronising the water simply because I have it on good advice that this low amount of clorine helps reduce parasites in the water and wont harm your fish at such low levels.
That's simply impossible. Imagine living in an airtight room that had a tube pumping oxygen in it. Then pour in massive amounts of carbon dioxide with the oxygen. You'll slowly, but surely, die. That's what chlorine does to the tank. And not only that, the reason they can stand salt is the fact that the salt you are using is not marine salt. They cannot stand marine salt A BIT.
The spike below their eye is a mechanism that rips through their skin when they're scared or above water. They take out the spikes (one under each eye) and flail like mad to hit the aggressor. But don't worry, they dont do this in the tank, so they cant harm your fish.
How big is the tank? Loaches grow to a good 1 foot and are used as food in Malaysia. So 5 feet of fish is a lot...
