...I'm not a big fan of fridging since I think that moving the animal introduces an additional stress factor that can have a negative impact on an already stressed animal. I also think that since it slows the metabolism it sometimes prolongs a problem that could be resolved more quickly through proper husbandry.
Bayhicoach offered some great advice, but I want to dispute the above paragraph. I realise Bayhicoach is only offering an opinion, but the post in general is so good that I worry future readers of this thread, might be persuaded to agree with him and delay in
fridging their axolotls believing the process could cause their pet unnecessary stress.
Fridging is a tried and trusted method of destressing and detoxifying axolotls. The initial move might be stressful but it's short lived and could be the difference between having a living or dead axolotl.
By
fridging them you are lowering their metabolism and removing them from other factors which could be causing their problems.
Lowering the axolotl's metabolism also increases the efficiency with which it excretes waste and is therefore unlikely to prolong any problem - in fact, quite the opposite.
Leaving your axolotl in a potentially toxic environment while you improve upon any poor husbandry that may have caused the problems will certainly prolong the suffering of your pet and will without doubt delay its recovery. Any problems caused by poor husbandry should, if possible, be addressed once your axolotl has been removed.
I have no desire to appear confrontational over this, as I've said, it's because the rest of bayhicoach's post is so good that I fear his opinion might persuade some that fridging their pet could cause more stress related problems, when I believe the consensus of opinion among experienced keepers would favour fridging as a valuable and often vital process.
