actually quit using the cycle - this won't help it at all; and how long has your tank been running - around the same time as you put your axie in or longer? The plants may help with ammonia but if your tank is uncycled and your axie has been in since day 1 of your cycle then; and you haven't done a waterchange or tested your water for the 3 things i mentioned then your axie is getting sick and stressed due to a: heat and b: possible ammonia levels.
Don't put icecubes in it; two reasons if it's just tapwater it can kill at worst or make your axie even sicker and icecubes cause fluctuating temperatures which can be stressful for axies. I wouldn't worry about the temperature at this stage. Most importantly deal with your axie.
Firstly, take your axie out of the tank and put him in a container of dechlorinated water; a tupperware one, or other plastic one that has a lid. This is just in case your ammonia levels are high and causing the skin to "break"
I think you should fridge him for the next day or two until you test your tank for ammonia/nitrites and nitrates- this will slow his metabolism down and allow him time to destress and possibly heal without the added stress of heat increasing.
As long as your fridge temperature is above 4degrees celcius, he should be fine. (ours is usually 5-6 degrees celcius when we fridge our sick ones) To check your fridge temperature, place a glass of water with a thermometer in back of the fridge and check it in 30minutes.
If temperature is above 4deg; then put the lid on the container, wrap it in a teatowel (to stop temp fluctuations and light flashing from opening door) and place him in the fridge.
You will need to do 100% complete waterchanges, and as he has fungus (rather than treat with melafix/pimafix) do twice daily saltbaths (2-3 teaspoons of salt per litre/pint for 10minutes -15minutes maximum).
Keep a few bottles of dechlorinated water in the fridge too (the waterchange and saltbaths have to be the same temperature as the one he's been in; otherwise you could stress him); or alternatively one bottle (empty soft drink bottle) of dechlorinated water and use another container with lid - filled with dechlorinated water. This extra container can be used for the saltbath or waterchange (whichever you decide - probably easier for saltbath).
Add the salt to this one just b4 time to do a saltbath, transfer your axie into this first saltbath, then just transfer him straight back into his chilled hospital container and place him back in the fridge. Wash out the saltbath container using a mixture of baking soda and water and rinse well, then fill with dechlorinated water and return to fridge.
When time for 2nd saltbath; follow as above, but while he's having the bath, wash out his hospital container with baking soda and water, rinse and fill with the bottle of chilled dechlorinated water, in the bottle in the fridge. Once bath is finished return axie to this one and clean out his saltbath container.
Sounds a lot of work, but it's worth it, if it helps to destress him and get rid of the fungus. Also, the fridge will slow his metabolism down so he may not eat if your fridge temperature is lower than 8 degrees celcius.
Now back to your tank! While he's in the fridge, take a sample of your water to the petshop (use any foodsafe container (I use vegemite jars - washed only with baking soda and water never detergents); and ask them to test for ammonia, nitrite and nitrates. Get them to write the figures down and come back here and post it.
(Don't let the petshop try and sell you quick fix remedies/things to try and get rid of the ammonia like ammolock, if your tank is cycling this doesn't help at all.)
Cycling can take anywhere from 2/3 weeks up to 8 weeks.
Is your tank length about 60cm x 30cm wide? I'm taking a guess, cos I'm useless at guessing litres; if it is it's okay size for one axie.
Does he have any other tankmates and what size is he?
And, don't forget to read the cycling article, if you haven't already, its very important.
