Temperature problem

I must agree, I have never had this problem, right now I 2 tanks a hige one and a tiny one both are displaying 30c on a night like to night and the fish are all lively and happy.

Make sure you have a lot of oxygen been pumped into the water and a good circulation. I like to use a power head on the opposite of the tank to where the water comes back into the tank from the filter to create a circular flow. I use the power head with piece of airline tube to suck air into the water stream. Most of them are supplied like this. And works better than conventional air pumps.

MOST importantly of all, double up on your water changes when its hot like this, to minamize the ammonia build ups and spikes. This is what usually kiils the fish, not 30c water.

Hi,2 days ago the temperature was 39 Celsius,I have 2 storage boxes outside with 20 guppies in it,I left the lid open and put a air pump in as they where all hangin around the surface

 

39 is very high and possible to start picking up problems but 30/31, if water is good and enough oxygen your fish should still be fine

 

Oh,I see,what do you suggest I do

 

I have them In 2 storage boxes

 

I would add an air pump with an air stone there.. sorry, I don't see one

Make sure the boxes are in a shadier and cooler part of the garden, if possible, somewhere where there is usually a bit of a breeze fan works but Im not sure if its possible to put one where you have the boxes

 

Thanks, will take the advice

 

Hi,can I ask you one more thing,my one guppie started looking it tail and lost a bit of colour,what do you think is the problem?

 

Lossing it's tail

 

I've got 2 laptop fans on my tank. (50 mm, 5 v). One is blowing into the canopy and other out. Evaporation is bad but no condensation on inside of canopy.Water temp steady at 27 deg.
