Hi I'm hoping someone can reassure me....I've had my axolotyl almost 4 years now and he survived my care surprisingly as I didn't do anything right, not having any idea about cycling and partial water changes, etc. Since being online I have learnt heaps but the local aquarium shop says I should continue doing things incorrectly as my axie has gotten used to it! I always completely empty his tank putting him in a bucket while I do so. I do put water conditioner in and then put him straight back in! I now know this is completely wrong but he's survived amazingly! He eats a block of beefheart every evening and doesn't waste any and now and again I buy him 10 neons for a treat which usually go in a few hours! My quandry is that he's developed a black mark on his body. Its just an isolated patch like a birth mark or something. Reading all about fungi, etc. has made me worried that it could be something like that? He's happy and healthy in all other respects.....can you please advise what this black mark could be?
Thanks you!
Thanks you!
