Extinction: There are no living specimens of the animal available. Extinction may be total, or an animal may be 'extinct in the wild', meaning there are only zoo specimens available. Biological extinction is defined as animals continuing to exist, but with no viable production of young (Lonesome George: http://www.tortoisetrust.org/articles/george.html).

Extirpation: An animal no longer occurs in an area of its historic range.

Extirpation: Within the context of animals and plants, means the eradication of a species or subspecies from a portion of its natural range.

Eliminate 'extinct/extinction' from this thread as it is defined elsewhere in the glossary.

    Hi guys, I was wondering if I possibly crashed my tanks cycle? I’ve had a cycling tank for months now, changing 25% water weekly. I never had any problem until a few days ago when I did a 50% water change. I did this because the tank was looking extra dirty for some reason and also I siphoned too much water out trying to vacuum the sand. I noticed since that water change, my axolotl has been hiding more, barely eating, and only moving from time to time. I checked the water perimeters and they are .25 ammonia, 0 nitrite and 10 nitrate. I normally have 0 ammonia, I haven’t had above 0 since I was first cycling the tank. Did I make an error or is this just a fluke? What should I do?

    Im worried about my lil girl, she’s normally fairly active and a pig when it comes to food. Should I tub her until I figure out the tank situation? Am I overreacting lol?

    Also, she is about a year old. Her tail is perfectly straight and her gills are perky (not curled forward). She’s looking perfectly fine, just acting weird

    Sorry one more thing, when I changed the water last I removed a few plastic plants that I realized were taking up too much room. Would the removal of the bacteria on the plants mess it up?

    Maybe, I’m not to sure. I’ve done lots of research when i got my baby axolot. Maybe she is just adjusting to the new tank?

  • Toothpickthelotl:
    @Nioa, ok, do you know why it might’ve spiked? I just did a water change a few days ago and tested all the perimeters and it was at 10 nitrate
