I've diagnosed the fish with ICH, I only want to use medication as a last resort, so I'm trying the heat method, I'm wondering how long should I keep the temp at 86? should I be doing water changes and vacuuming during the process? can my goldfish handel what seems like a really high temperature? What might of possibly caused the illness in the first place?
Any tips tricks and advice is much appreciated.



Gold Fish are hearty fish they can adjust to temperature as long as it's temporary. You would do the heat treatment for about 2 weeks. That's usually the cycle of ich. I believe daily water changes are required and you will need to vacuum the bottom of the tank as well.


The temperature is able to kill ich by itself so you won't need meds. I'd add an airstone to be sure there's enough oxygen for them at that high of a temperature but other wise they should be fine until the temp hit like 90. Do daily water changes and gravel vacs with the temp at 86 and you'll be golden.

Great! Thanks a lot for replies!


if you're using a spray bar on your canister and getting a lot of surface agitation, you don't have to add an air stone.

keep the heat on for 2 weeks. you can just continue to do weekly water changes, but you should be doing atleast 50% to remove wastes, and vacuuming.

many fancy goldfish are bred and raised in outdoor ponds in the sun in tropical areas, like Thailand, Malaysia, Philippines, Hawaii, Florida, and Brazil.
