Weird lumps and bumps

I was just curious, has anyone else seen these weird things in their axolotls? We recently gave our girl a salt bath because her gill filaments were getting shorter and shorter every day and we thought maybe there was a bacteria or something eating at them very, very slowly. The gills seem to be on the mend again now, but I've been keeping an eye on a lesion on her side for the past couple of months, and just in the last couple of weeks noticed a new lesion on her tail. The salt bath made no difference to either of these weird things.


Side lesion, just behind her foreleg, about a third down the length of her body. It's about 2cm long, 1 cm wide and kind of wiggly. I can't see anything that would indicate a parasite in the area. It looks like a scar, but it's definitely growing, you can't see it as obviously in earlier photos.


Tail lesion, appears as a filmy white blister on the top edge of her tail. Nothing appears on the opposite side, other than a slight indentation.

Aside from that, she's pretty happy, eating well and enjoying her new green algae-free tank. The lesions don't seem to bother her, I don't see her scratching or anything. The gill issue, as well as the lesion on her tail I noticed occurred after we had that annoying green-water problem that we've managed to clear up through more plants and daily water changes.

It's a mystery!

Have you thought about taking her to the vet? Is your tank cycled? What temperature is your tank? Has your axolotl recently had any feeder fish?

Hi Neo

To answer your questions: No, Yes (ammonia and nitrite 0, nitrate 5ppm), 18 degrees Celsius constant and No She's had the bumps on her side since we got her, but it's slowly getting bigger.
