Hillstream loaches are river fish, which means they require high levels of flow for them to survive. And if I am correct, they are still not extremely hardy even with the high levels of flow, but do not take my word on it. The first thing that came to my mind, was that they are being oxygen- deprived. So what type of filter(s) do you have?

But, I would imagine that even a hillstream loach would be able to survive longer than just 3 days without adequate oxygen. So, we will need the actual numbers for Ammonia, Nitrite, and Nitrate, as "fine" cannot help us nearly as much as the exact numbers.

See the wind, smell the water, taste the fire, hear the earth.

Yes what Taylor said.

They need high flow, high oxygen, and are VERY sensitive to nitrates. So what exactly is your 'fine' Nitrate reading?

In my tank anything above 10ppm and they got really stressed and climbed the walls out of the water.

Without friends everything is for nought.

There is an article entitled "A River Runs Through It", written by Martin Thoene, at .  It gives you a step-by-step of how to build a tank that is suitable for long term survival of hillstreams.  Several people here have had experience with Hillstreams.  Some with the type of tank Martin describes.

Jim Powers--another mod at studies that type of loach as well.  As do some of the members.  Unless you are willing to structure a tank to their specific needs do not keep them.  Definitely a just add water fish.  Definitely not a type of fish that will survive in a standard tank.  Special care is required for those very special fish.

Flow and dissolved oxygen like the others said. 

If you go by Loaches tell the two guys I said hello--and give Shari a kiss for me.  Great people.  They also authored a book about loaches--It is available through this site in the books section of the board.  Buy it--it is incredibly beneficial in helping you understand the world of loaches--and even hillstreams.
