A low concentration is ok but you'd be safer with a salt bath (and a little salt in the water any way). A salt bath is 4 or 5 teaspoons of salt (table salt, cooking salt or aquarium salt, not "low"/"low sodium" salt though) in a litre of water. Put the axolotl in that water for 10-15 mins, then take it out and put it back in a tank of clean water with about a half teaspoon of salt in it per litre - it's safe to leave them in that concentration of salt all the time. Don't leave it in the salt bath itself for more than 15 mins though or you'll do more harm than good.
Repeat the bath perhaps twice a day for a few days. It should get rid of the fungus. However, you need to establish what caused it in the first place. I think it's likely, since you live in Australia, that it's too hot in the axolotl's tank and this is the cause. You need to keep axolotls at 24 degrees Celsius or lower. At 25 they will succumb to stress. Keep in mind that it's better to keep an axolotl at 25 or 26 degrees constantly rather than adding ice cubes or such to the water to cool it, which will cause rapid fluctuations throughout the day. So use a more stable method of cooling (frozen 2 litre coke bottle or some such).
Thanks for the reply John. Sorry I took so long to reply myself. Aristotle (My axies name) started to lose the fungus but now it's come back again. Funny thing is I have two other axies & they haven't got it at all. It may well be temperature related & I'll buy a thermometer & check it out. Will let you know how they're doin next week. Merry Xmas. Paul.
@sde, hi everybody I'm getting a tiger salamander coming from Katy Texas what are the shipping conditions that's okay to have them shipped to me in the state of Vermont it's just starting to get the temperature low above 45 but it may be too hot to ship him any thoughts or ideas on how to work this out
I currently have a 3 year old axolotl, he hasn't been eating for the past couple of weeks and has lost a lot of weight. Hedwig usually eats bloodworms and earthworms just fine but now he won't even stud it. I've done a water change to make his nitrate lower and his water is at a good temperature
Hey guys I was wondering if my axolotl looks fine to you he/she (still don’t know) I’d activate and eating as usual but I did notice veins in the tail area.. let me know what you guys think! Also if anyone could tell if it’s a boy or girl that would be great! (Zolo was eating a worm and pretty sure the worm pooped XD)
