What can i do??

Today is really hot, and the temperature is in the high 20's©

In the tank are, little fry, possibly tench, gold fish and koi...

Is there anything i can do to keep them cooler.

Or will they be fine with such a high temp?

for a start put ice in a ziploc bag and float it around the filter output. I usually keep a couple of bottles with frozen water in them and just drop them in the tank for the 2 real hot days we get per decade. HTH

Im not running a filter though, as it may be to much for the lil guys, also i have been advised not to.

I will put some ice in though, thanks!
