Up to which temperatures

[aurora]

I have a 200 liter tank for my loaches(Sewellias, Beaufortias, Nemacheilus binotatus and (not really a loach) stiphodons). This tank is on the first floor where the temperature of the water never reaches higher than 27 C(usually it's around 22 degrees). Now I would like to move them to a 160 liter tank on the second floor. The problem is that the water there gets up to 30 C in the summer when it's really hot.

So my question is, up to which temperatures can I keep my fish healthy.

I also have a empty 54 liter tank on the first floor so if 1 or 2 species can't be in those high temperatures they could be moved there.

To get a fast answer, go to http://www.loaches.com/.

In the upper right corner is a search box. Enter your fish name there and it will give the correct temperature for each one. (if they are loaches)

That's why I ask it here. The max temperature for the sewellia would be 23.8 C but they have done well when the temperature was 26-27 degrees. I get that for a longere period of time the best temperature would be aroud 22 degrees, and that's what the fish will get. But I would like to know if they will be ok when the temperature will be 30 C for a couple of days in the summer.

For a few days to a week; yes. For longer periods of time, I would think no.

Have good aeration and they should be fine. Some tips for cooling are to take the covers off, switching off light during the day, have a fan to blow on the surface if possible. These tricks help a little.

All these fish will tolerate higher temperatures IF they are provided with adequate oxygen. This means lots of water-movement and surface disturbance for gaseous exchange.

Sustained periods of elevated temps are likely to be detrimental to the fishes' overall health and may affect longevity.

Like Janma already mentioned, having fans blow across the water can drop the temp several degrees.

I have 2 4,5volt terrarium fans on my hillstream tank, and even with the hot period we had in Holland a few weeks ago the temp never went above 24 degrees even if it was 32 in the room.

Mind you, it evaporates 2-3 litres a day
Whatever makes the fish happy.

anyway, computer fans work just as well provided they don't get soaked with sprayed water.

Thank you all for helping me.
When it's that hot I usually shut down the lights and I remove the cover. Ik could try building something with computer fans, to help cool it down even more.

So with good movement in the water and survace and possibly an air pump they should be fine. That's good to hear.
Thanks all
